Shadow Island #17

Shadow's Doom

Rate this book
Ice cream, you scream
Welcome to my murder scene.

Sheriff Rebecca West and her team may have ended the Yacht Club’s debauched reign, but things on Shadow Island haven’t calmed down. In fact, it's taken on a more terrifying form. Sensationalist headlines accuse Rebecca of everything from conspiracy to corruption, but the real danger isn’t in the ink and whispers. Something worse has washed onto the shores of Shadow Island.

And it can kill in a single bite.

A local man has fatally overdosed on fentanyl at the ice cream parlor after polishing off a salted caramel cone. No history of drug use, no needles, no signs of addiction—only a body filled with poison. Rebecca suspects something far worse than a tragic accident. But how does fentanyl find its way into a dessert?

When a father and his two children are poisoned by fentanyl after eating at a local diner, Rebecca comes to a startling realization. A sadistic killer is playing a dangerous game of chance, turning routine moments into fatal traps. The island is no longer just haunted by its past—it’s under siege by a faceless killer, lurking in every bite, every sip, every breath.

Instead of a bullet, he’s randomly placing poison around town in a deadly game of Russian roulette. No one is safe. And any unsuspecting citizen could be next.

Shadow’s Doom, the horrifying seventeenth installment of the Shadow Island Series by Mary Stone and Lori Rhodes, is proof that the power to kill is the most addictive—and deadly—drug of all.

Will Rebecca win this battle and will Shadow Island be doomed after this?
Catching up with Sheriff Rebecca West and her Deputies was great. Following this series has been nice. I keep hoping Rebecca will win against the forces threatening her and the Islands people.
In this book there is another attack on the Islands people. Will Rebecca be at this crime? Stop the damage it has already caused. How scary is this threat and will they catch the men involved.
Exciting! You should read it too. You will love this Series and Author.

Someone is poisoning the residents from Shadow Island with Fentanyl. Someone has randomly poisoned something at each restaurant in the small town, deadly amounts of the drug. 3 people die, and two children barely survive an overdose. During Sheriff's West investigation, she learns this may not be random and caused by something or someone from her past. Never a dull moment In the Shadow Island series.

It had been a while since I visited Shadow Island and caught up with Rebecca, Hoyt, Vivian, and the rest of Rebecca’s team.

Rebecca was strong, intelligent, and probably braver than was safe for her own good. I was glad to see the amount of support she had from her Shadow Island friends and the community.

Once again, this book gave me the same sense of unease as previous books in the Shadow Island series. The author has a way of making you wonder what kind of people behave like this. You know people like this are out there, and you can only hope you never encounter them.

This book was not as graphic as some of the previous books in the series, but it still left me strongly affected by what happened.

One thing I had forgotten about this series is that the story is always ongoing. There are usually several interlocking aspects of the crime. Rebecca and the gang may solve one part of it, but there is always something else lurking in the shadows. To add insult to injury, just when Rebecca thinks she might finally be able to take a breath, a new—and sometimes even more heinous—crime lands in front of her.

Both this book and the series as a whole are intense, disturbing, and exhausting. I can usually read one, maybe two books from this series in a row, but eventually I reach the point where I need to read something much lighter. If you are looking for a light read, this is not the one.

SHADOW’S DOOM is the seventeenth jnstallment in the Shadow Island Series by Mary Stone and Lori Rhodes and another frightening story you will have a hard time setting down.  

They thought by taking down the Yacht Club their Island would be a safe place to be. Since then girls are found partially buried. Now people out for a bite of food are dying. First a local man stops for an ice cream cone. He drops dead before leaving the shop. Next it's a family at everyone's favorite café on the Island, leaving one dead and two children in the hospital. It's quickly found to be from fatal overdoses of fentanyl in their food. Someone is playing a deadly game of Russian roulette and any unsuspecting citizen could be next. At the same time Sheriff Rebecca West is being targeted with dark rumors and insinuations against her reputation and ability to serve the public. It will take law enforcement and forensic teams from surrounding areas to help solve these cases.

If you haven't read any of Mary Stone's books and enjoy mystery thrillers, you should start. I did receive an ARC of this book from the author and this is my freely given and honest review.  I recommend this book and the entire series.

Sheriff Rebecca West and her deputies have gotten rid of the Yacht Club and are hoping for the Island to get back to normal. However, there is a smear campaign spreading vicious gossip about Rebecca pertaining to her past and claiming she is the reason for all that has happened to Shadow Island since her return. Then, a man dies after eating an ice cream cone. Pure Fentanyl is found in his system. Is this an isolated case or are they looking at a murderer putting this drug into local eateries?? The story is really good and educates the reader about how dangerous even a speck of Fentanyl can be.

Shadow's Doom is the seventeenth book in the Shadow Island series by Mary Stone. This collection of twenty books (so far) is a gripping ride through mystery, suspense, and human darkness.
With former FBI agent Rebecca West at the helm, the books masterfully weave high-stakes investigations, layered characters, and island secrets that kept me on edge.
Each installment balances chilling crimes with deeply personal stakes, rendering Shadow Island both a paradise as well as a nightmare.
This is a fast-paced, twist-filled, and psychologically compelling series - a page-turning must for fans of thrillers and atmospheric mysteries.
Happy Reading…

Rebecca and her team are suddenly faced with a victim dying at the local ice cream store.. Their investigation shows fentanyl in his body, but how and where did it come from? He has no signs of being a drug user. Before they can solve this death investigation they get a call that a husband and 2 of his children are in need of medical help quickly. They find fentanyl in each of their systems also. Now the big question is where is it coming from and how is it getting into peoples systems.
Very fast paced with a surprise ending

Another big win for Mary Stone and Lori Rhodes with Shadow’s Doom. They have crafted a story with superb characters and is so good it is hard to put into words! From chapter one the suspense builds and builds. This new case is so fresh but also connecting it to Sheriff Rebecca West’s past is brilliant!
The ending chapters are so important to Rebecca’s back story. Then new information comes to her relating to her parent's death and her near death after being shot. What will she do with this information???
And the cliffhanger…WOW!!

Just when you think Shadow Island is safe, it's not. Someone is still out to get Sheriff West, and they are pulling out all the stops. A smear campaign is launched and then a killer comes to town. An old enemy has surfaced and Rebecca as well as her entire community is in danger. I like this series, and Sheriff West is one determined woman. Lots of twists that you aren't expecting, and this book will keep you involved. I read it in one setting. Can't wait for the next one!

Well THAT’s a twist.

Trying to be as spoiler free as possible here. I had no idea where the new storyline could possibly be going after the main one wrapped up in the previous books. It felt like it was going into murder soap opera territory. Finishing the 2nd half, especially the last few chapters of this book made it make total sense. After the blindside hit me I’m just left facepalming about how I didn’t see it coming. GG Mary

The slander, drugs, murders, crime continues even after Yacht club is shut down. This tense thriller is real page turner. The past is catching up with Rebecca and the horrible truth is coming up. What will she do as a sheriff and as a person?! This is another amazing book in the series with the cliff hanger at the end. Mary and Lori wow. Thank you.

Shadow Island has been through a lot and so has Sheriff West and her deputies. The calmness of the island is shattered by a possible fentanyl death. As they investigate the death another call comes in involving two children. What is happening to the island? Who would want to cause the chaos tearing the island apart and why?

Oh more scares on our favorite Island

Another, oh my story the ending is yet to show it's self but not with more hints, scares and I'm sure murders yet to come . I am so glad the Sheriff's learned she is loved by all of the deputies and she isn't all alone as she feared. Read and enjoy and then join me while I impatiently wait for the next Shadow Island book!

Shadow's Doom( Shadow Island FBI Mystery Book 17)

OMG!!!!!!! This book was amazing and terrifying. It is scary to know that only a tiny speck of fentanol can kill a grown man and how easily someone could poison random people. I truly hope no one ever tries this. And now Rebecca has another big problem to deal with I can't wait to read the next book

Page turner

Mary Stone never lets us down! Another gripping Shadow Island book. I think I read this one even faster than those before. And now we are left on the edge of our seat for the next book. Worried to death about Rebecca and praying she nor another deputy die. It's too heart wrenching when we loose a main beloved person in the small community.

There’s nothing as disconcerting as people eating their favourite meals in their favourite restaurants and ending up dead or fighting for their lives. This is what happens in Shadow Island and the sheriff Rebecca and her team need to figure out before more danger continues lurking in their town. It was worth the read.

3 1/2 stars. Someone is putting fentanyl in the food supply at Shadow Island. After a man dies in the ice cream shop and a father and two children pass out in the sandwich shop, Rebecca and the rest of the force are racing against the clock to find who and why.

Enjoyable story, I will be sorry when this series ends.

Seems like the evil never ends at Shadow Island. Now someone is after the innocent people of the island. But why? The answer is in the book. I am glad to finally learn what happened to Rebecca and her family before she arrived at the island to live. I voluntarily reviewed a copy of this book.

A man dies after eating a seemingly innocuous ice cream cone. What caused his death will leave you afraid, very afraid. Follow along with Sheriff Rebecca West and her deputies as they unravel the mystery.

Mary Stone has hit another home run with this one!

Excellent

A fast paced read into the chaos and corruption caused by one man's overriding greed and addiction fueled by another man's self entitled need for revenge & power. It's a scary tail that rings clearly in the climate we face today.
