Storm Warning finds wildlife biologist Alex Carter in Hawaii trying to protect and study endangered hawksbill turtles. It wouldn't be a suspense book though if there wasn't something else going on. Lots of things are about to go down.

A massive hurricane is approaching which means Alex and her volunteers are desperately trying to move turtle eggs to safety out of the storm surge. At the same time a group of poachers/thieves have been committing terrible acts in Alaska and the high seas. While Alex has had to face some troubles on the beach she won't be prepared when this large group comes to shore and takes one of her volunteers hostage.

I love all the details about sea turtles. Everything is described so well and I learned a lot. The author's and Alex's love for wildlife comes through. Hawaii is a great setting and the beginning of the book has a "calm" vibe to match. A few things are happening that Alex has to take care of. Meanwhile only the reader knows what's really coming.

When it does come it's almost a shock because everything automatically shifts into high gear. From that point on it's nonstop action. Alex is smart and brave and she puts herself in the middle of it. The reader travels all around Hawaii with Alex as she battles animal smugglers and a hurricane. It becomes a true fight for survival which I greatly enjoyed.

I love everything about this series. The setting, the atmospheric writing, the characters including the animals, the suspense. It's just great!

Thanks to Netgalley for the chance to read!

Book #5 in the Alex Carter series. As a wildlife biologist, she travels to Hawaii to study and protect endangered Hawksbill sea turtles during their nesting season, where she recruits volunteers. A massive hurricane approaches and the team races to move the eggs to higher, safer ground.
Armed thieves take eggs and one of Alex's volunteers as a hostage because he can provide access to a paleontology museum, where the big prize lays: a frozen mammoth, with a dangerous pathogen. The showdown was a bit too far fetched for me. 2.5 stars, rounded up.

While I appreciate some of the info in the book (global warming and endangered species), it made the book read less mysteriously/suspenseful than I’d have liked. Certain parts of the book were bogged down with oddly specific details and it lost my attention. Overall, interesting concept and it could have been a good story, but fell flat for me

Wow! "Storm Warning" is a page-turning thrill ride from beginning to end! I just loved it! Alex Carter, Wildlife Biologist, has accepted a new assignment on the Big Island of Hawaii, to monitor and ensure the successful hatching of a group of endangered Hawksbill turtles discovered near a now paused resort construction site. She arrives and sets up her beach camp site, and monitoring equipment, while she recruits local volunteers to aid in protecting the nesting site. She is determined to protect the eggs and the hatchlings as they make their trek across the sand to the ocean. All is going well, and Alex is enjoying her new assignment and a bit of peace, until dangerous poachers and a monstrous hurricane threaten it all. Alice Henderson has written a brilliant, exciting plot, filled with danger, suspense, and plot twists that swirl from Hawaii to Alaska, and England! Her knowledge and love of wildlife is evident on every page! The character of Alex Carter that she has created is quite an amazing, courageous and dedicated woman, who is determined to do everything she can to save endangered species from all threats, environmental and criminal. I learn so much from these books! (example- meaning of anthropogenic climate change) I love turtles, and have visited many rescue areas, and beaches with protected areas for the eggs, so this book was of particular interest for me. The afterword and information sections at the end are really informative. Can't wait to Alex's next adventure! Thank you to the author, publisher and Netgalley for my advance copy. The opinions of this review are my own.

These Alex Carter wildlife biologist suspense books just keep getting better and better! I loved this latest set in Hawaii that has Alex working to help sea turtles when she gets caught up in a dangerous biological weapons scheme that a wealthy billionaire is trying to steal and release onto the public with the aim of having the only vaccine to save the world.

A horrifyingly possible scenario that has Alex running through volcano fields and hidden volcano bunkers/tunnels trying to outwit the thieves. Highly recommended for fans of the Clive Cussler NUMA files/Dirk Pitt series.

Informative, action packed and filled with facts about endangered animals and climate activism. There's also a great cameo from Alex's love interest towards the end! I can't wait for the next book in the series!! Many thanks to NetGalley and the publisher for an early audio copy in exchange for my honest review!

I have read each and every book in the Alex Carter series and I couldn't wait to get my hands on the latest one! Number 5 in this series, Storm Warning has an intriguing premise and our main character, Dr. Alex Carter is at her very best. If you love smart, resilient women, you will love Dr. Carter the wildlife biologist. This latest installment keeps the reader on their toes with a fast paced mystery that keeps the reader thinking. I learn so much about the environment, wildlife and nature each time I read one of these books and I am also wildly entertained! Thank you to the publisher, NetGalley and the author for the ARC of this novel in exchange for my honest review.

Thank you to NetGalley and the publisher for allowing me to read this.
I wasn't sure the direction this book was going to take as it was teaching you about turtles and the works of what Alex was achieving.
But then the high stakes came in with the storm/poachers and had great gripping points where I myself felt I couldn't breathe reading a certain scene. How things kept happening was very page turning, but also had me making faces with have it was gross and descriptive.

Disappointing

While the descriptions of wildlife and the efforts to prevent extinction are always interesting and informative the books in this series have become completely unrealistic. The focus on the evil bad guys instead of the attempts to preserve species made this book unreadable for me. The perpetuation of the hatred of "Big Pharma" had me unable to read past the halfway point. Too bad the author didn't stick to what they excel at- educating about endangered species in an interesting made up story- rather than trying to turn their main character into a cross between Jack Reacher and Jason Bourne.

STORM WARNING (ALEX CARTER #5)
BY: ALICE HENDERSON

I fell in love with this talented Author. Alice Henderson's very first book called "THE SOLITUDE OF WOLVERINES." which is still my favorite which I picked as a random discovery. This author has created in her Main Character one of the best,intriguing, and a protective of all Wildlife especially an endangered species named Alex Carter who is a Wildlife Biologist. I have often thought that this author is just as devoted to raising awareness how in nature these dwindling in vast amounts certain animals in Wild life are vulnerable to not just Climate Change. With how groups albeit hopefully few poachers that are motivated by greed. How some people pay no attention to laws that protect these shrinking amounts of animals, and how few have just as low regard for not only killing these animals, but take it one step further, and easily kill Wildlife Biologists who are tasked to work in their habitats like Alex Carter who always will defy, but make it her mission to stand up for these animals that are possibly going to be extinct. Another reason that these animals face danger is by land developers who are going to make a fortune by building on land that is where these protected species are being forced to leave by driven off their land that is become conservation dedicated to these animals. I have read every single novel, and the lengths that some people go to especially in this latest one, installment number five called, "STORM WARNING," have the same disregard for human life by leaving no one left to tell by eliminating all witnesses.

I really love learning about all of the latest technological tools such as also admirable about Alice Henderson's including the scientific ways to be able to track these animals which in this case with Alex Carter's gear that is like a GPS Satellite that she puts on these Hawksbill Sea Turtles that are effective to be able to locate them underwater. As well, as Alex's whole host of other Scientific other gadgets. Each subsequent novel I get to learn from Alex about different animals, like in this book she's in Hawaii, with how Alice, and her volunteers that watch out for these Hawksbill Sea Turtles that when they built their nests on land, and I was very interested when they lay their eggs each one has the capacity to lay between approximately 140 to 150 eggs each which I was grateful to learn. Never would I have known that which I felt like I keep learning new things each novel allows me to learn and also appreciate how with each different part of the world that Alex is on assignment I know about the animals, but educates me on specific characteristics about that animal that I didn't know. With this one also her initial plan was to ensure that when these baby Sea Turtles hatch she is there to guarantee they would make their trek across the beach unimpeded from human or other predator's don't interfere with their safe passage to their destination. There's a hurricane expected and any part of that storm could be cause for concern that this author and her excellent character development of Alex Carter has made Alex the most lovable characters in any series she is kind, determined, well educated, looks our for others that are being harmed like how she stepped up help Jerome in the beginning by saying something to that police officer and he seemed to know that he is being observed which seemed like his incentive to stop crossing the line by using excessive force.

One of Alex's Volunteers gets abducted. There's a group of poachers, or Smugglers that go to that beach. Alice tries to get that volunteer out of the position of being captured.

As with all of these novels these are people that are up to no good and dangerous so on top of the positive attributes that I listed above there is danger and this novel has plenty of chilling scenes. For example it starts out with the discovery of a several thousands of years old Woolly Mammoth that was frozen and then there's murder of unexpected victims. There;s all of that positive attributes above with a very intelligent Author who delivers a very intelligent Biologist that the credibility is there since her scientific well explained non harmful but gentle different intriguing equipment that with it very evident that Alex, and Author, Alice Henderson love the animals that makes this series, and this latest novel captivating enough. There's also the main character who is likable, determined, and brave. There's suspenseful thriller events that ratchet up with intensity that this one felt like it happened more often which I thought some aspects were a stretch, and I found like most thrillers with my having to suspend disbelief. I think it is such a clever series that I thought it disappointing since most thrillers in the past five or six years don't need to lack credibility so the fact that I don't read them, and this author is so brilliant but except for a few authors of thrillers that I still read that don't go way over the top like this. I wish I could let this Author know that she is increasingly taking a brilliant premise, and adding more thriller content which lacks realism which in my opinion is affecting my desire to continue reading them. I think the thriller aspect is not needed, and less of the thriller theme would be returning to her great concept since her first book I loved, but each one has more of what is implausibility, and maybe it's me but this author should not write action since it is not believable.

Alice Henderson's thrilling and fascinating series about Alex Carter, a wildlife biologist whose past adventures have had her studying jaguars, wolverines, polar bears and caribou, now takes her to Hawaii. In STORM WARNING, Alex has been asked to monitor a beach where hawksbill turtles are laying their eggs. The timing is perfect as she is just coming off of another job and has the time. Also, returning to the island where she lived with her parents for a while brings back fond memories.

As with all of Henderson's books, this one starts with a seemingly unrelated incident that will be relevant later in the novel. In Alaska, a gold mining crew uncovers a woolly mammoth. It gets shipped to Hawaii for study, but then a baby mammoth is discovered at the same site. Before much can be done to carefully excavate it, a helicopter appears with masked men. Not only do they take the diminutive baby mammoth, they kill everyone there.

Then the action moves to the beach, where Alex is snorkeling over a vibrant coral reef. One of the ways in which Henderson keeps the stories enthralling and filled with scenes we love to imagine as we read is to describe the wildlife that Alex is viewing in such detail that we easily can picture it in our minds. We see the sunlight playing over the coral and the "iridescent amber and brown" of the rare hawksbill turtle she observes eating sponges that grow on the reef. By breaking off pieces of the sponges, thus opening the reef, the hawksbill allows fish to reach places that they wouldn't be able to access otherwise.

Alex sets up camp on the beach and recruits volunteers to help her watch the turtle nests filled with eggs. She can't be there every minute, and when she needs to go to the store for food or other supplies, someone else will ensure that predators like dogs, raccoons and humans don't disturb the nests. As we find out, humans can be the deadliest predators around. One of the volunteers is a scientist at the nearby Museum of Vertebrate Paleontology, where the Alaskan mammoth was originally taken for study.

While Alex is trying to count endangered turtle eggs and shield the nests, she's also protecting the wildlife in the ocean from illegal gillnets that kill indiscriminately. It traps one of the turtles Alex has tagged with a sensor, so she is able to save the turtle and remove the gillnet. A hurricane is approaching, and Alex will have to figure out how to move the eggs to safety so they don't drown in the storm surge. That turtle eggs need protection from drowning is one of the many fascinating things that we learn about wildlife in this series.

As the storm approaches, the real bad guys appear. The events from the prologue make sense as we see the ensuing danger to Alex, the museum and the world at large. Alex becomes almost a superhero as she dodges and intrepidly takes action to stymie the villains. It's like watching a movie where we know you don't go into the basement because the monster is there, but the character does anyway. That's what we feel as Alex makes move after move to thwart the evil plan of a billionaire who will never be satisfied with his money.

Henderson writes what so many people feel these days about billionaires trying to control everything --- what the media reports on, what networks air, who is allowed in our country, who goes to war and who profits from it: "And why was it that the richest people seemed to be the most obsessed with acquiring more wealth, even turning to unethical means to get it?" (Billion-dollar trades in oil mere minutes before public statements about war come to mind here.)

What I and many readers adore about Henderson's novels is the wealth of information she provides about not only the species that is the main creature in the story, but others as well. Here we learn about how climate change is decimating the population of sea turtles. "Turtles get killed in staggering numbers when they get caught in fishing nets. They're also crushed by dredges used in shellfish hunting. They're even sucked up by nuclear power plants that use seawater to cool their reactors." Henderson goes on to explain that humans also harm turtles by building resorts and housing developments on beaches where they nest. Seawalls rob the turtles of their egg-laying beaches, and climate change causes more destructive storms that erode beach habitats and drown turtle eggs in their nests.

While each of these books can be treated as a stand-alone, the overarching story about Alex and her family; her best friend; and Casey, the mystery guy, makes it a great series to dive into from the start. It's incredibly rewarding to read a novel that incorporates real information about our world and our wildlife, a fabulous protagonist and gripping action, while also being quite touching.

If you enjoy eco-thrillers, crime thrillers, and action thrillers, then look no further than Alice Henderson’s series featuring wildlife biologist Alex Carter. The fifth book in the series, Storm Warning, is set in Hawaii and mainly on Honu Beach near the small town of Anuenue. Alex is camping on the beach to study and protect hawksbill turtles who have started nesting on the site.

She’s looking forward to a break from the danger of her past assignments. First, she discovers poachers, and then, as a massive hurricane approaches, armed thieves storm onto the beach while Alex and her volunteers are trying to move turtle eggs to safety out of the storm surge. They abduct one of the volunteers and Alex goes after them.

Henderson has become my favorite author who emphasizes different facets of nature in a mystery thriller. The book starts with a prologue in Alaska and a horrifying event. It will take readers a while to understand the importance of this event and how it fits with the rest of the story.

Alex is a likeable character who is three-dimensional and had depth. She is a skilled wildlife biologist, adept at martial arts, and is an expert shooter. She enjoys solitude, but has a few very good friends. She’s also polite, curious, determined to make a difference, has strong beliefs and ideals, and she enjoys meaningful connections and communication. She’s most at home in the wilds and is a bit lonely at times. She’s supported by an array of secondary characters that enhanced the story, but were not as fully developed. However, the relationships seemed believable and not contrived and provided the needed support or conflict.

As usual, the world-building is fantastic. I felt like I was transported to Hawaii as she carried out her research and encountered some dangerous situations. The story is descriptive and gives readers an opportunity to learn about the endangered hawksbill turtles as well as some of the other wildlife on the island. The story was compelling, shocking at times, intense, and a great addition to the series. While some of the action is over-the-top, it did not reduce my enjoyment or enthusiasm for the book. Themes include endangered species, climate change, wildlife trafficking, murder, greed, grief, friendship, and much more. At the end of the book is information regarding wildlife and the environment, including books and documentaries on sea turtles and nonprofit organizations that help sea turtles.

Overall, this combined mystery, nature, the environment, action adventure, crimes, and survival into one fantastic novel. It’s entertaining, compelling, and kept me rapidly turning the pages. Not only was this a fascinating mystery that kept me fully engaged, but I learned a lot about the hawksbill turtles. If you enjoy action-packed thrillers with an environmental and threatened wildlife theme, then this is a series to consider reading. I can’t wait to read the next book in the series.

William Morrow and Alice Henderson provided a complimentary digital ARC of this novel via NetGalley. All thoughts and opinions expressed in this review are my own. Publication date is currently set for March 24, 2026.

Thank you to NetGalley and to William Morrow for the ARC of Storm Warning by Alice Henderson.

This is a great addition to the series, and, for new readers, this is the 4th book in a series, so while you could sort of jump in without issue, I think it's still best to start at the beginning or else a few character mentions/interactions might be ruined.

In this adventure we join Alex in Hawaii, where she is monitoring/studying/protecting hawksbill turtle nests. Thing are generally peaceful besides one unfortunate encounter with poachers, but when a hurricane moves toward the island, trouble comes directly to Alex's beach in multiple big ways. As she moves the turtle eggs from the beach with her volunteers, one of them is taken hostage by masked gunmen, and with service down and the storm surge moving in, Alex is the only one capable of helping.

That's really all I can say before the story really kicks off in the Alex Carter Attack fashion - where the story moves in really wild ways and Alex is there to take and give the punches.

These are such entertaining reads, and they're an environmentally-centric mystery thriller that should really be giving male protagonists like Jack Reacher a run for their money.

Henderson speaks so passionately and knowledgeably about the environment and animals, but she also provides such wild entertainment with everything Alex finds herself capable of.

I took off a start for some generally mundane reasons:
- Alex is SO capable against criminals in every book, but whenever we're with her she's just eating pasta or protein bars and hiking about. I would love to see more of her actually training in her martial art moves or with guns or any of those things that she never struggles with when the danger is afoot. I think I need more than just "My mom taught me this" because some of these things require a lot of effort/strength.
- In the first book Alex thought more about the impact of the near shooting in Boston / her own safety. By the fourth she's in pretty wild danger in every book, but we don't get that same level of reflection. I kind of wish in some way she would acknowledge some sort of impact that being forced to kill others, run for her life, have friends killed, etc. has had on her.
- Casey. WE NEED MORE CASEY. But also, Alex still struggles so much with Casey being vigilante murderer without acknowledging that she too does not shy from murder when faced with protecting herself. Yes, Casey's situation is still different, but honestly, Alex walks that line very closely too without recognizing it in herself.
- While Casey generally is the connecting thread between the books, I think we've lost an overarching subplot since book 2. That's totally fine if these are meant to be one-offs for fun, but it seemed like originally there was an intent for more here.

I super love this series and can't wait to see what Alex gets up to next.

Storm Warning, the fifth book in the Alex Carter series, takes the wildlife biologist to the tropical shores of Hawaii to monitor endangered hatchbill turtles laying their eggs on a remote beach.

Henderson's latest offering follows the formula of her previous novels in the series, with Alex getting a brief time to enjoy the beauty of nature around her, followed by encounters with people that don't have nearly the same sense of appreciation that she does, and then Alex trying to outwit and outlive the villains in the story. Reoccurring characters periodically pop up, in this book her friend Sasha from a previous adventure makes the largest appearance, though her best friend Zoe and another friend Casey show up briefly as well.

Each book Henderson writes is informative about a different endangered animal and the perils they face that are often a result of people. Previous books have covered wolves, polar bears, and jaguars in different locations around the country, and she keeps up her trend of moving to a different climate and animal here. She also has the opportunity to introduce some secondary characters that help move the first part of the story along and who show that there are still plenty of people out there that want to do their part to help protect wildlife.

Sometimes I feel like the books get a little too bogged down into trying to present climate and animal facts. They are interesting, and it's a more engaging way to reach people than dry reports, but it can also take away from the thread of the story. This still happens here, but maybe it's the presence of enough other characters that Alex can explain information to that helps it feel less like a train of thought truly aimed at the reader.

This book has two running storylines of threat - poachers that are interfering with Alex's efforts to protect the turtles, and a group of mercenaries pursuing the remains of a preserved wooly mammoth that has been brought to a local museum. The latter ends up being the more predominant storyline and is probably the more interesting one, but it does tend to stray away from the more wildlife at risk theme Henderson tends to go for.

It also creates a whole chunk of the book that DOES get bogged down with Alex playing cat and mouse across the Big Island with the mercenaries during a hurricane. It includes the introduction of a lava tube that was used as a World War II bunker, which is really interesting, but the rest of it feels overly drawn out and for me, drags the book down. I was more than happy to see Alex make a return to civilization to move the story forward. I wish Henderson had devoted less time to this 'scene' and more time to wrapping up the story.

All in all, it's another solid cli-fi suspense novel that fans of the genre will enjoy. It won't knock your socks off, but it's an interesting and information read.

A complimentary copy of this book was provided by the publisher. All thoughts and opinions are my own.

The Alex Carter books are all well written ecological thrillers that are also a call to action. Each book is centered on an endangered species, and you learn quite a lot about each one through out the story. These books are sort of like a nonfiction book with a thriller storyline and a main character that you can root for. Alex travels the US to help endangered species while also taking on some bad guys and winning.

I listened to the audiobook and Eva Kaminsky does an excellent job portraying Alex and the other characters in the story. She does a great job with the accents of the other characters, even the australian one. She keeps a steady voice when Alex is in danger, just like I imagine Alex’s inner voice to be.

I really like Alex. She is very smart and usually well prepared for any situation. She also cares deeply for the environment and the animals around her. She is a scientist who has a lot of empathy, not only for animals, but for people too. She is also a very determined young woman who is strong willed but also vulnerable. She has shown some growth in her characters over the course of the books, and has learned some restraint as well. She no longer just jumps in to rescue others, but takes a moment to assess the situation and makes a plan. Alex tends to make friends wherever she goes, but due to the nature of her work, is also often lonely.

I always enjoy the secondary characters that Alex meets in each book, even the bad guys are always interesting. These characters are always well rounded and we even get a bit of backstory on each one that makes them feel well fleshed out. In this book we even get a few chapters from the main bad guys which I really enjoyed.

The world building is, as always, phenomenal. The author does a really good job of describing the setting and the animals that Alex encounters. I felt transported to Hawaii and reading this made me want to visit it again. The dialogue is also well done, and I loved some of the heartfelt discussions Alex has with her volunteers and her friend Sasha.

Even though I really enjoyed this story, it did push the boundaries of incredulity a bit farther than the other ones have. Especially towards the end as the bad guys are chasing Alex across the island during a hurricane. But the author does a great job making you think that it could really happen. I also really enjoy all of the information about hawksbill turtles and some of the other animals that Alex encounters throughout the story. The nonfiction information can sometimes drag the story down, but it is always interesting and usually important to the rest of the story.

If you enjoy eco-thrillers, crime thrillers or any kind of thriller, than you really should give these books a chance. A bookseller recommend the first book in the series, A Solitude of Wolverines, and I am so glad I listened to her. You don’t have to read these books in order, most work well as a standalone, but it is always best to start at the beginning.

🌪️Storm Warning by Alice Henderson
Alex Carter Series #5

Alice Henderson’s Storm Warning is a pulse-pounding fusion of environmental suspense and action thriller, set against the lush yet volatile backdrop of Hawaii. With her signature blend of ecological urgency and high-stakes drama, Henderson once again delivers a story that’s as intellectually engaging as it is emotionally charged.

🦜 Wildlife biologist Alex Carter arrives in Hawaii to study and protect the endangered hawksbill turtles, hoping for a reprieve from the danger that has shadowed her past assignments. But paradise proves deceptive. As a massive hurricane barrels toward the island, armed intruders storm the beach where Alex and her team are relocating turtle eggs. When one of her volunteers is taken hostage, Alex’s pursuit leads her to a paleontology museum—and into a deeper conspiracy with global implications.

🌱 Henderson’s narrative is rooted in ecological advocacy, but her stories are never preachy. She explores the fragility of ecosystems, the ethics of conservation, and the human cost of environmental crime. The hurricane becomes more than a plot device—it’s a metaphor for the chaos unleashed when greed collides with nature. The novel asks: What does it mean to protect something that cannot protect itself?

🧩 Alex Carter remains one of the most compelling protagonists in contemporary suspense. She’s not a superhero, but a scientist with grit, empathy, and a fierce sense of duty. Her evolution across the series culminates here in a portrayal that balances vulnerability with tenacity. The supporting cast—volunteers, locals, and even the antagonists—are drawn with nuance, avoiding caricatures.

🌋 Henderson’s Hawaii is vivid and immersive, from coral reefs to storm-lashed beaches. Her background in wildlife research lends authenticity to every scene, and the tension between natural beauty and looming disaster is palpable. The island isn’t just a setting—it’s a character, alive with danger and wonder.

Storm Warning is a standout in the Alex Carter series, marrying suspense with substance. It’s a novel for readers who crave thrillers with heart, intellect, and a conscience. Henderson proves that protecting the wild isn’t just noble—it’s urgent, and sometimes deadly.

Alice Henderson combines wonderfully engaging mystery writing with issues that teach and inform. She not only proved us entertainment, she teaches us valuable lessons about the animals we share this planet with, and how we can help protect them. I LOVE her Alex Carter series, and I eagerly "snap up" every one! 😉

Storm Warning by Alice Henderson is a wilderness thriller that follows Alex Carter, wildlife biologist, on one of her assignments to protect endangered species in Hawai’i. It will be published in the United States on March 24, 2026.
Overall, this was a satisfying next installment in the series, with facts about ecology and wildlife interwoven with an intriguing plot and relatively fast-paced with some action sequences. It fits squarely into the eco-thriller or wilderness thriller genre.
I have read almost all of the books in the Alex Carter series. I was excited to read this one, because the new setting in Hawaii and the focus on sea turtles are both favorites for me! As I read the book, I enjoyed learning more about the lives and habitats of endangered sea turtles. The setting was crafted well too, set on a remote section of the Big Island of Hawai’i.
As I read though, at times I was a bit puzzled. Alex did not seem to react to some of the dangerous or violent events. Early in the book, she disentangles a turtle from a fishermen’s’ net and they tried to attack her, but she doesn’t seem to have any emotional response to it at all, even though she has a head injury. I would like to see more about the character’s emotions; even when she shared with her friend in about her last dangerous adventure, it seemed like she was summarizing.
At this point in the series, I would really like to get to know the character on a deeper level. While I enjoyed learning about new biology facts and following the exciting action sequences, I would like deeper character development, because Alex is an interesting character. I would love to see some characters from the past who returned, and this would lead to some hard decisions. The character of Alex Carter seems in stasis, like she is not growing or learning new things about herself from each of her adventures. I would love to see her as part of a duo so she would have someone to talk with and plan with during much of the book. Overall, I would like to see more of a character arc in the next book in the series.
Thank you to William Morrow and NetGalley for an ARC in exchange for an honest review.

Great descriptions of nature and creatures, like in the previous books in the series.

Did I look up hawksbill turtles on Wikipedia to see what they look like? Of course I did.

This book is harrowing! The villains are infuriating. May all psychopaths spontaneously combust.

This series is not only entertaining and riveting--and it has a great heroine. But it's also educational. For instance, I learned that TURTLES BREATHE THROUGH THEIR BUTTS.

Page 88: Junglefowl. Feral chickens. Wow!

Page 126: %@%%!!!!!!!

Page 270: Since Alex puts on a 1940s gas mask, I thought, "Are you my mummy?"

Glad I don't live in a place that has hurricanes. We have awful pollen allergies (right now), wilderness fires since 2016, occasional ice storms, & volcanoes, but at least we don't have hurricanes.

This is a vividly realistic thriller but also an educational book. In back is a list of sources for learning about turtles & saving them.

Since the book features a mummified baby mammoth, I searched for "baby mammoth" on the interwebs. A baby mammoth was found in Siberia in 2024:
https://archaeologymag.com/2024/12/50...

This seems a bit uncanny: Shortly after I read in this book about the need for boats to slow down for the sake of wildlife, I saw an online ad from the Center for Biological Diversity on the same topic--the toilet demon regime is trying to make it legal for boats to speed in the presence of whales (or something like that). Of course the rapey toilet demon & his predatory regime are against everything that's good.

Some Kegsbreath fuckery, because of course:

Crime against wildlife is surging.

Alice Henderson has taken this serious theme throughout her Alex Carter Series with this one being the fifth novel. I read the first book in this series, A Solitude of Wolverines (2020), and really enjoyed it. Looks like I need to return to the other books as well. Storm Warning does read as a standalone and Henderson will set you on the path right away.

Our story opens with a group of archaeologists who have uncovered a surprising element in their recent dig in Alaska: a fully formed woolly mammoth encapsulated in the perma frost. But leave it to Henderson to throw a stick of dynamite into this mix of happenings. Someone wants that woolly mammoth intact and they're willing to cause great harm in the process.

We'll turn the temperature way up as we hit the Honu Beach in Hawaii. It's there that Alex Carter, a wildlife biologist and main character of this series, has pitched her tent on the sands. She's there to protect the endangered hawksbill turtles who have come to deposit their eggs on the beach. Alex incorporates a reliable group of volunteers to help her in her watch as the eggs hatch.

Now Alice Henderson doesn't just line her novel with cute little turtles swimming towards the ocean. Too simple. Henderson does complicated, intricate, and harrowing storylines. Someone is sending poachers and bad guys to interrupt this steady flow of Nature......and they'll do it in life threatening ways. Hang on. Alex Carter is not just an outstanding cerebral character, but she does kick ass on a hierarchy plane of total action.

Storm Warning is an intense read. Henderson fills us in on quite the plight of Nature in the world. Her Author's Note is very informative. But some of the circumstances are a bit contrived and over the top. Cut Henderson some slack in the process. It's all in a day's work to fight the baddies who have no environmental consciousness. They do deserve a bad end. And just how does Alex Carter make that happen? Crack this one open and grab some rain gear. There's a hurricane on the horizon.

I received a copy of this book through NetGalley for an honest review. My thanks to William Morrow and to the talented Alice Henderson for the opportunity.

Alex Carter has tracked polar bears, wolverines, jaguars and caribou. She has traveled and faced danger from frozen ice floes to deserts in her research. Now she has a chance to set up her tent on a beach in Hawaii to monitor hawksbill turtles. They are the victims of natural predators and poachers. With the help of local volunteers she watches over the turtles’ nests, waiting for the hatchlings to appear and ensuring a clear path to the sea. While it seems like the perfect assignment, it becomes more complicated when a hurricane takes aim at her location. There is also a group of mercenaries who kidnap one of her volunteers and kill another. A perfectly preserved wooly mammoth had been shipped from Alaska to a nearby paleontology museum for study. The director of the museum was one of Alex’s volunteers and they need him to bypass the museum’s security. As her volunteers evacuate the eggs to a safe location and prepare for the storm, Alex takes off after the mercenaries, fearing that the museum director will be killed after they get what they want. It is a life threatening battle through floods, storm surges and an abandoned WWII bunker hidden in the surrounding jungle.

Alice Henderson is a wildlife researcher whose love of nature shines through her stories. Alex takes the time with her volunteers to explain the hatching process as well as the effects of global warming on the turtles. Alex also reveals more of her past. Before her mother’s death as a military pilot, she taught Alex survival skills that have come in handy. Her father is an artist known for his nature scenes. Her upbringing instilled a love of nature that has been evident throughout the series. With action that takes you from an attack in Alaska to a chase through the storm tossed island, Henderson keeps the action moving. It will leave you wanting to join Alex on her next assignment. I would like to thank NetGalley and William Morrow Publishing for providing this book.

Storm Warning by Alice Henderson
⭐️⭐️⭐️⭐️✨️ (4.5 stars)

Thank you to NetGalley and the publisher for the ARC! Storm Warning releases March 24, 2026.

Confession time: it took me several chapters in, after I was already invested, to realize this is actually book five in a series. I started noticing references that felt like I was missing some context, so I looked it up… and sure enough, there are four books before this one. Normally I would pause and go back to the beginning, but I was already hooked and needed to see what happened next.

This story jumps in with a big, immediate hook, which is exactly what I love in a suspense novel. The whole thing gave me strong Jason Bourne vibes… if Jason Bourne were a woman whose mission also involved saving the environment.
The stakes are high, the pacing is fast, and I was engaged the entire time. One thing I especially enjoyed was how much real-world environmental and nature knowledge is woven into the story. You can tell Henderson knows this space deeply and has done meticulous research. I always find it fascinating when a fictional story includes elements grounded in real events, like the discussion of permafrost’s ability to preserve organisms, which I later learned has parallels to something that actually happened just a few years ago.
Henderson’s writing is action-packed and immersive, and her descriptive details made it easy to picture the stunning beauty of Hawaii (though I still hope to experience it in person someday 🤪).

Now that I know this is part of a series, I definitely plan to go back and read the first four books to fill in some of the gaps and experience more of Alex’s adventures. I’m also excited to see where her story goes next!

3.5 ⭐️⭐️⭐️

I’ve been reading this series for the last two years. I loved the first 3 books, especially the fresh combination of a thriller blended with factual wildlife conservation. As the fifth in this standalone series, I can’t say it stood out, but it brought the same animal saving - running from bad guys vibes that we do know and love.

This one had some new takes that I appreciated. There were different points of view from the poachers/thieves and their scenarios. There were some pretty gnarly chase scenes through storm drains and the Hawaiian wilderness. It was mostly not very believable, but still pretty harrowing to read. I also felt like the author really went there with some of the gore and deaths, she didn’t really hold back this time.

Overall, I think this book was predictable, it has a feeling like we keep trying to go somewhere, but never quite getting there. The story mainly follows the same plot every time. There’s recurring characters who have the same conversations in every book. We have to reread things we already know because it’s technically all standalone. For those of us who obviously have read them all, this has gotten a bit….old. But, if you know what you’re in for, you can still enjoy it for what it is.

I wish I enjoyed this one more. Sometimes it was really fun and other times I found myself zoning out. I still love the very real information about wildlife that we get from these books and the obvious passion that the author brings as well as her calls to action, but just know, this book doesn’t have the same magic that the first few brought.

Also, random, but I kind of hate that the titles don’t match anymore.

Thank you so much to NetGalley and William Morrow Books for letting me review this early copy!

Storm Warning is the fifth book in Henderson's Alex Carter series, and it's one of my favorites of the series.

Storm Warning begins on the scene of a paleontology dig where mummified mammoths have been discovered in Alaska. This discovery kicks off a series of events that have implications far beyond the permafrost.

Across the Pacific, Alex is currently in Hawaii studying sea turtles and trying to protect their nests from both human poachers and natural predators. However, a new threat looms as a massive hurricane is forecasted to hit the island. Sea turtle nests will be decimated by the incoming storm surge, so Alex will need to work quickly to save the future members of the vulnerable species.

Sea turtles are my favorite animal, so I was incredibly excited that Storm Warning focused on them. I also love paleontology, so the mammoth storyline was an unexpected bonus. Like most of the Alex Carter books, there is a lot of action in the later half of the book. Some of the action is improbable, but it's exciting nevertheless. There is a death in this novel that I can confidently say I've never read before; it was honestly kind of awesome considering the awfulness of the victim.

I always appreciate Henderson's inclusion of information and resources at the end of her novels to further educate her readers about the species and causes included in her stories. Her passion for the natural world is evident in her characters and how she always takes the time to offer a call to action.

Thank you to William Morrow, Alice Henderson, and NetGalley for the eBook advanced reader's copy! All thoughts and opinions are my own. Storm Warning will be published on March 24, 2026.

SPOILER ALERT

Alex Carter and her volunteers confront dangerous men who range from poachers of turtles and turtle eggs to those involved in stealing the Wooley mammoth and other artifacts from the Museum of Vertebrate Paleontology, a state-of-the-art facility near the beach where she is watching and protecting the new hatch of the endangered hawksbill turtles. She recruits numerous volunteers, one of whom will be killed by the mercenaries hired to get the mammoth.

The mammoth along with a baby are found at a mining site in Alaska. The mammoth is unearthed and sent to HI, while the baby is stolen (and then lost in a plane crash) while all the workers in the mining project as well as the archaeological site are murdered.

Alex will prevail after trekking through the dense jungle for days. The evil mercenaries will either be killed, die in the jungle or be rounded up. When Alex's friend Casey hears of the experience that Alex had gone through, he sees to it that Agatha Crowell, CEO of Advantageous Pharmaceuticals, who had instigated the crime, dies. She had hired a zoologist to find a pathogen that could be increased in strength. It would be loosed on the world, and she would have a vaccine that had already been designed to counteract the pandemic. Thus, making millions.

During the confrontation Alex and the volunteers will thwart the mercenaries, save the eggs from poachers and a hurricane. It is another exciting story that informs the reader of another endangered species.

Storm Warning by Alice Henderson is the fifth book in the Alex Carter series. Henderson focuses on an endangered species in each of her books, wolverines, polar bears, caribou, jaguars and now the hawksbill turtle. I know well the importance of marine preservation and turtles are near and dear to my heart, so I loved her bringing their plights to the forefront. This may not work for some readers, as the information comes off as very encyclopedia-like and not at all a piece of quality literary writing. But if you are of the science mind and enjoy learning about animals and their environment, you will enjoy parts of this book.
The main character, Alex Carter, is a conservation biologist, so she finds herself in unique environments with tasks to do for research on a certain species. There is always an action packed scenario of the bad guys doing something that affects her project so she gets involved. Alex is on the big island Hawaii for Storm Warning and ends up fighting the villains during a hurricane. Having personal experience with hurricanes, I can’t say I felt much of the action was authentic, s be sure to suspend some disbelief going into this.
But overall, because of the subject material, I really enjoyed this read. I hope it educates and encourages people to make life changes that help marine life from extinction. I know I will not look at a plastic bag the same way again. Thanks to NetGalley and William Morrow for my ARC.

We just had a major blizzard in Minnesota less than a week ago, so reading Alice Henderson’s
Storm Warning quite a contrast because it is set in Hawaii. As in the other books in her series, this thriller features wildlife biologist Alex Carter. Alex has camped out on the beach to study, monitor, and protect the nests of the hawksbill turtles. She recruits locals to assist her, and is enjoying the break from her previous assignments where she encountered harsh weather conditions and other dangers.

However, enjoyable that seems, it does not prove to be the case. She encounters all sorts of perils, both natural and man-made. Fortunately, Alex is one tough cookie. With tons of experience and training as well as loyal companions along the way, she to battles dangerous poachers, a fierce hurricane, and injuries, some deadly, to herself and her friends.

If you are someone who cares about nature and ecology, you may find this a quite enjoyable read. As thrillers go, this is quite a saga! The challenges just keep coming and coming and coming. A bit much, it seemed to me. Nonetheless, I found the book hard to put down and found it to be a satisfying read.

I received a digital copy as an ARC. Thanks to NetGalley, William Morrow, and Ms. Henderson. My opinions are my own.

Storm Warning is fast paced, high excitement from beginning to end! Wildlife biologist Alex Carter has accepted a new assignment to ensure the successful hatching of endangered Hawksbill turtles at a paused resort construction site on the big island of Hawaii. Upon her arrival, she sets up her campsite and monitoring equipment on the beach and starts to recruit local volunteers for the project. She is determined to protect the eggs and the hatchlings on their long trek across the beach to the ocean. She is enjoying her new assignment and a little bit of peace and quiet, until a group of dangerous poachers and an impending massive hurricane threaten it all. Alice Henderson has written quite a thrilling plot filled with danger and suspense. The plot takes Alex from Hawaii to Alaska and England! Her character of Alex Carter is a dedicated protector of wildlife and endangered species! She is quite courageous woman! I love turtles and have visited many beaches with hatching areas, as well as turtle rescue facilities, so this book was of particular interest for me. As always, I learned so much from this book, including from the afterword and information sections at the end. I am looking forward to the next adventures of Alex Carter! My wife did receive an advance copy from the author, publisher and Netgalley and I am very glad she did. The opinions of this review are my own.
