Don't Ask Why: A Thriller

by Steph Nelson

She hoped this girls’ trip would help her heal. Instead, it just might kill her.

Still reeling from her husband’s death, Courtney joins her three best friends on a secluded island in the Florida Keys. But everyone has a secret and the getaway meant to bring peace quickly spirals into chaos.

First comes a rumor about a woman who was recently killed on the island. Then the property manager is nowhere to be found. When a stranger shows up at the vacation rental and one of the friends goes missing, Courtney starts to wonder if they’ll make it home at all.

There’s no Wi-Fi. No cell service. No way off the island for four days.

But four days is too long to wait for help.

If Courtney wants to survive, she’ll have to fight for her life.

✨Maybe that’s just how grief operates. Maybe you don’t ever get past it, but rather, you absorb it. Make it part of who you are✨

What to expect -
🌊Fast-paced survival thriller
🌊Girls’ trip gone wrong
🌊Secluded island setting
🌊Short chapters
🌊Grief and loss of a loved one
🌊Dark pasts and secrets
🌊Strong bond between women

This was such a short and fast-paced read that had me constantly turning the pages. Courtney has recently lost her husband, and when her sister-in-law and best friend ask her to join them on a girls’ trip, she agrees reluctantly because it was her husband’s last wish. What she doesn’t expect is for this trip to completely turn her life upside down and leave her fighting for survival.

The first half had me screaming at these women for all the dumb decisions they were making 😭 Like, after seeing all the red flags this trip was throwing out from the very beginning, I would’ve turned back on that same boat immediately. But what do these women do instead?! They make excuses for every warning sign and willingly move onto the private island🙂↔️

But once things started getting dangerous in the second half, that’s when the book truly gripped me and refused to let go till the end. So many secrets were revealed, and seeing everyone’s true personalities slowly come out in the open made this such a thrilling read.

The only things I didn’t like were the men in this book and Tori’s obsession with astrology. Every time the women brought up something genuinely alarming, the men would immediately brush it off and act like the girls were just being paranoid for no reason. And the douchebag Tori brings to the island?? He was so judgmental and annoying that I completely understood why the other women kept saying she had terrible taste in men😭

As for Tori herself, she’s actually quite a complex character with a difficult past. She’s found comfort in astrology, and whenever things spiral out of control or she feels a panic attack coming on, she tries grounding herself through astrological facts. That, I could understand. But when she started analyzing every single person based on their rising signs and personality charts, it genuinely started annoying the shit out of me🥲

Other than that, I genuinely enjoyed this one. I loved seeing the women overcome the tension between themselves and stand by one another even when it meant putting themselves in danger. And Courtney slowly finding her spark again, learning to live with her grief, and choosing to hold onto the beautiful memories while continuing to make new ones was honestly so moving by the end.

Overall, if you want a quick thriller with female characters making questionable choices, getting themselves into dangerous situations, and fighting hard to survive, you definitely have to pick this one up.

✨Pre-read:
Secluded island and girls' trip gone wrong?! Hell yeah🤭😍

"But the truth is, you can't control when the waves of grief decide to pummel you. They're in charge. Always."

This is a twisty little delight that will keep you guessing! Four women go on an island vacation to help one of them grieve the death of her husband, but when they arrive, it's not the peaceful getaway they expected. Between rumors of a woman recently killed, the missing house manager in charge of food supplies, and one of the friends bringing her new boyfriend, tensions are high—and then one of them vanishes.

With rotating POVs of the women, an isolated atmosphere, and plenty of hidden motivations and secrets, the pace and tension never let up! Each woman is vastly different with a distinct, fleshed-out personality, making their dynamics more compelling. All the conflict, drama, and danger are superbly brought to life for the audiobook by narrators: RACHEL FRANCO, DEVA MARIE GREGORY, JENNIFER McCOOL, and ABIGAIL RENO. I highly recommend this exciting, evocative listen!

Yes, this is a fabulous destination beach-read, yet STEPH NELSON also touches on deep themes of terminal illness, grief (written so accurately I teared up), and trauma, with a strong focus on female friendship. You'll need to hang on tight for twists and turns—many of which took me by surprise—that are grounded perfectly into the layered plot, with a riveting, action-packed ending. Readers who love a fun, gripping, suspicion-laden read with heart won't want to miss DON'T ASK WHY!

I’m sure Courtney was not expecting this awful girls trip that she received after trying to grief the death of her husband! This story had the perfect set up for a good thriller, secluded location, no cell reception, secrets among the group, missing host, rumors of a previous “incident”. I enjoyed the alternating POVs and hearing the story told in first person from these characters made the story better. One thing for sure, and that was unexpected is how their lives were intertwined in shocking ways. Fans of Steph will absolutely appreciate this one, but if I was telling a new reader to dive into her catalog I would recommend The Final Scene first. Thank you NetGalley & Ticking Clock Press for a reader copy.

They’re grieving and need a girls trip. It’s just what they need. Laughs, drinks, good times.

But ohhhh this trip goes sideways real quick when one of the girls goes missing and nothing is going as planned.

I loved this one. The three characters and each of their personalities really showed here. How they interact to the same situation in such difference ways, was something that kept coming to my mind. We don’t always get this much character building in a 200-250 page thriller - while not losing any of the thrills.

That’s one reason Nelson will forever be one of my favorites. The story starts kind of slowly - suspense wise - but the emotional building is brutal and necessary. You will feel this one to your soul.

🎧: Full cast you just have to listen to this one. Fabulous listen. Followed along while listening and the narrators bring this book to life in a whole other way.

Also loved the little special dropping we got of the author’s real life and the birth signs and other thriller books.

What a fun book. Grief, survival, friendship, twists - this one has it all.

Final Thoughts:
Oh, well at least you knew it was coming - I cannot say this enough: NOTHING can prepare you for what it’ll actually be like. How it’ll actually feel. And there’s a flip side of that coin because it’s much worse having to watch them dying in front of you for years or months, with no means to help them. You’re helpless. THERE IS NO COMFORT JUST BC WE KNEW IT WAS COMING. NONE. (Not to the author - she just hits on this topic.)

Until next time…

*3.5 stars*
​Don't Ask Why is a fun, propulsive thriller that is great book to read in a single sitting. If you’re looking for a book with incredible momentum that you can easily fly through, this one absolutely fits the bill. The writing is smooth, accessible, and wastes no time getting straight to the point.

​The mystery itself is a bit of a mixed bag. A few of the plot twists are fairly predictable, and seasoned thriller fans will likely spot the breadcrumbs early on. Because of that, some of the reveals lose their shock value. However, Nelson still has a few tricks up her sleeve. Just when you think you have the whole thing figured out, the story delivers some genuinely surprising pivots that catch you completely off guard.

Ultimately, Don't Ask Why is a highly entertaining, fast-paced popcorn thriller. It has its predictable moments, but the sheer speed of the story and the strength of the unexpected twists make it a thoroughly satisfying weekend read.

[The Hateful Reader · Rating 3 out of 5]

Four friends who see every red flag and wave right back head off on a vacation and promptly abandon all sense of self-preservation.

At a certain point, the characters are so committed to making bad decisions that you start thinking… maybe survival isn’t for everyone.

There are flashes of intrigue and that “wait, what’s happening?” energy… but the astrology subplot goes on forever and totally distracts you from the tension of the story.

At this point I may need to retire believability as a standard for books, because apparently we’re just doing whatever now.

I did have the chance to meet the author (she is so warm and personable), which makes me want to like this more… but this one just didn’t land for me the way I’d hoped.

Not my favorite of Nelson’s books. Still loved meeting her… if we run into each other again, I’ll pretend I was hacked.

I received an ALC of this audiobook through libro.fm in exchange for an honest review.

Picking up a new mystery can be like a box of chocolates - you never know what you're going to get. Steph Nelson is a new author to me, so I wasn't sure what kind of read this was going to be. However, I've recently read quite a few new mysteries that wound up being over the top, so I went into this with somewhat reasonable expectations, in my opinion.

This wound up being a good way to pass some free time, with the perfect setting to convey a claustrophobic, impending-doom-type location, on an isolated island in the Florida Keys with no one coming in or out. We are introduced to the four characters in the friend group who are going on this vacation because one of the friends was recently widowed, and her deceased husband planned this trip. Unfortunately, I found it difficult to differentiate between the four women, who have extremely similar inner monologues and patterns of behavior. The audiobook is narrated by a full cast of four narrators: Rachael Franco, Deva Marie Gregory, Jennifer McCool, and Abigail Reno, which should have made it a lot easier to figure out who was who, except that each of the narrators sounded so much alike that I was really only able to identify two voices, since they honestly all sounded the same, both voice and tone of their inner thoughts.

The plot starts out slowly, and sets the scene for a locked-room thriller on an island with no way on or off. The setting itself felt almost like another character, and I was enjoying it as the characters get settled in, only to discover something isn't right. The middle part of the story picks up quite a bit, although it has some predictable twists and turns early on. That changes quickly, with some completely unexpected plot twists, and occasionally veering into over-the-top-ness, but I was still along for the ride.

Overall, this was one of those thrillers that a fellow blogger calls 'popcorn books' because they require a little more suspense of disbelief than others, and don't feel as realistic. Going into the read expecting a popcorn thriller made a big difference for me, and I was able to adjust my expectations. Ultimately, it was one of those reads that is enjoying while you're reading, but afterwards you can't remember anything about it.

This was SO much fun! I love a fast paced, tense popcorn thriller and this was literally perfect! I loved all the different twists, the multiple POVs and the juicy secrets sprinkled throughout. This is a perfect book to throw into your beach bag and get lost for a bit.

I’ve read all of Nelson’s work and each one is slightly different, which shows her diversity, creativity and style. One thing she does so well is her depiction of grief. It’s always accurate and handled with care.

Grab this and take a staycation for a bit!
Thanks @stephnelson for my copy and I loved your reference to your besties work (Noelle W. Ihli)

another thriller that is easy to read and hard to put down! I enjoyed that I didn't have to think too hard while reading this one - I just got to jump into the story. there were a few times where the book slowed down but read a few pages and it picked back up.

After the loss of her husband, Courtney decides she needs a break from everything life has thrown at her. So when the opportunity comes up for a girls’ weekend away on a private island, she takes it. But what’s supposed to be a relaxing escape quickly turns into something far darker.
First, there’s the unsettling story of a girl who was murdered on the island years ago. Then the housing manager is nowhere to be found. And before long… Courtney vanishes.
With no way to leave the island and no way to contact the outside world, her friends realise they’re completely cut off. Determined to find Courtney, they start digging for answers, but it soon becomes clear that someone on this island is hiding something. And they’ll do whatever it takes to make sure no one leaves.

Let’s start with the negatives. None of the characters were particularly likeable. They all had tragic backstories that connected them in more ways than one, but I never really found myself rooting for any of them. The constant astrology references also started to feel a little repetitive and slightly grated on me after a while.
That said, the story itself was definitely engaging. It’s a fast-paced thriller that kept me guessing as the mystery slowly unfolded, and I found myself trying to piece together what was really happening on the island and who might be behind it all.
Overall, this was a solid, entertaining thriller with an eerie isolated-island setting and plenty of twists along the way.

⭐️⭐️⭐️

Don’t Ask Why by Steph Nelson had all the ingredients of a fun popcorn thriller. The short chapters made it incredibly easy to fly through, and the premise hooked me right from the start.

After one woman loses her husband, a group of friends decide to escape on a girls’ vacation to a private island. One of them brings along her new boy toy, and what starts as a relaxing getaway quickly turns into something much darker. Secrets begin to unravel, and when the man hosting their stay on the island isn’t who he claims to be, everything spirals into chaos.

The twists definitely kept me guessing, but somewhere around the middle, the pacing slowed down for me. I found myself skimming a few sections because it started to drag, and I wasn’t quite as engaged as I was in the beginning.

That said, the ending pulled everything together nicely. All of my questions were answered, the twists made sense, and I appreciated how everything came full circle. While it wasn’t a home run for me, it’s still an entertaining psychological thriller that fans of quick, twisty popcorn thrillers will likely enjoy.

A girls' trip to a private island was always going to end badly, wasn't it?

Following Courtney as she tries to rebuild her life after the loss of her husband, this quickly turns from a relaxing getaway into a tense survival thriller packed with secrets, disappearances, and plenty of red flags that had me questioning every decision these women made.

The isolated island setting worked really well, and once the danger started ramping up, I flew through the second half trying to work out what was really happening. The short chapters and fast pace made it a very easy book to binge.

I didn't particularly connect with the characters, and the constant astrology references started to wear a little thin, but the mystery itself kept me invested throughout.

Overall, a fun, fast-paced thriller with an eerie setting, plenty of twists, and a strong focus on friendship, grief, and survival.

This is my second Steph Nelson book, and like with the first (Last One Out), the action begins immediately and THEN the character building begins. I really, really enjoy books written this way. If Steph Nelson has no fans, I'm dead. Love her!

I feel like this storyline had really good potential but wasn't written very well or had much thought put into it. The parts that mention astrology are very repetitive and unnecessary. Also I couldn't help noticing how often she mentioned the mangrove trees 🤣

[Kimberly · Rating 3 out of 5]

I loved Steph Nelson’s other book, Last One Out and was so excited to receive an ARC for her new book. Unfortunately, this one didn’t work for me. I found the cast of characters to be sad and unlikeable each one with their own tragic backstory. The astrology part was fun but became too repetitive. There were references to drug abuse, addiction, and foster care abuse. In the author’s defense there were trigger warnings at the beginning of the book, just wish I saw them before I requested.

Thank you NetGalley for the ARC!

BLURB:
Courtney Gray, recently widowed, joins her friends Paige, Reese, and Tori on a secluded island in the Florida Keys for a short getaway. The trip quickly turns tense when rumors of a past murder surface, the property manager disappears, and one of the women goes missing.

REVIEW:
If you haven’t read Steph Nelson’s thrillers before, this book is the perfect place to start and shows off what she does best. It’s now my second favorite book of hers, only behind Last One Out—an absolute must-read! This book is a fast-paced, multi-POV psychological thriller that barely gives you a minute to breathe! The story has great tropes woven in—an isolated location, a group cut off from the outside world, a missing person mystery, and a race-against-time narrative. There’s also lots of emotional depth through its main themes of grief, fractured female friendships, and betrayal.

The book opens with a gripping prologue set a year earlier that creates unease before the main timeline starts. From there, the story follows a single present-day timeline via the POVs of Courtney, Paige, Reese, and Tori. The dynamic between Paige and Tori immediately has friction and makes you wonder what secrets both women are hiding. Courtney’s grief is the emotional core of the story—the details of the loss of her husband are slowly revealed, and her reflections on their final moments together are some of the most emotional scenes in the book.

As things start going wrong, all four women begin to look suspicious. Once one of them goes missing, you’ll be second-guessing everything as their group dynamic constantly shifts. The male characters—Rawson and Leslie—are both unlikable and questionable from the start, so predicting who the real villain is isn’t easy in this one!

The best elements of this book are the consistency in intensity and pacing. From beginning to end, the story is always moving forward with constant tension—either from uncomfortable dialogue or action scenes—and there aren’t really any repetitive inner monologues or unnecessary scenes, which is SO refreshing! The second half is very unpredictable, with twists that even experienced thriller readers will find hard to predict. At times, you‘ll feel like there are loopholes in the plot or details that aren’t fully explained, but Nelson does a great job of circling back and resolving all of them by the end, showing a very well-laid-out plot! The final chapters include a high-stakes climax followed by a satisfying resolution—and you’ll be wanting to pick up another Steph Nelson thriller very soon!

This is the second book by Steph Nelson that I’ve read this year and I am really loving her thrillers. Don’t Ask Why is centered around 4 friends that go to the Florida Keys after one of their husbands dies. The dynamics between the girls is very tremulous and as the story progresses you find out why. Each of the girls is hiding a secret, but there’s a bigger problem lurking on the island. I really enjoyed how the two subplots of the story were combined and after the main resolution there were still twists being thrown at you in regard to the girls secrets. I felt like I was able to figure out part of the ending, but then again I really couldn’t because so much happened in order to bring this story to a close. This was super entertaining and I definitely think this will be a fun summer read!

I listened to this via audiobook thanks to @libro.fm.

Thank you LibroFM & Simon Maverick for this audiobook!

This was such an addictive read. It had so many successful elements - a group of friends going to a secluded island, mix up of hosts and multiple twists along the way. Our protagonists have secrets of their own and the author did a good job at talking about their backgrounds and life. While some I feel were not very likeable, the dynamic between the personalities did create extra drama and entertainment along the way.

As the book progresses, the suspense builds and it becomes more action packed. I was holding on to the narrators words, excited to hear about the reveal. The ending was good, however didn't completely blow me away. It did however, have multiple revelations and things that readers would not expect - so overall I do call this a success!

Overall, Dont Ask Why is an addictive and totally bingeable thriller, about a group of friends on a secluded island and a culprit who does not seem to want them to leave - perfect for a thriller lovers summer or those craving a beachy themed read.

3.5/5

[Ty · Rating 3 out of 5]

This had the ingredients for a great thriller, but something about it didn’t really connect for me. I liked the setup- a girl’s trip on a remote island along with the secrets, tension and heavier themes like grief woven throughout the story. While I felt for the characters and understood what they were going through, I never became fully invested in them or their journeys. At times, the flashbacks and reflections on the past pulled me out of the main storyline and made the pacing feel slower. I did enjoy some of the twists and revelations and there were some things I didn’t see coming. Overall this won’t be a memorable story for me.

Thank you to Simon Maverick, an imprint of Simon and Schuster, for the free copy for review.


Thrillers - especially on audio- are some of my favorites. So I was excited to have the opportunity to listen to this one on Libro.fm as one of my Simon Maverick choices this month.

Don’t ask why follows a group headed on a girls trip to a secluded island off the Florida Keys. One of the character’s husband’s has died, and she hopes this trip with her friends helps her to relax, heal, and move forward. Once the girls arrive, strange things begin happening that make the girls begin rethinking this trip. Suspicious rumors, creepy people, no WiFi, and no way off the island. These friends band together to fight for their lives.

[Karin · Rating 4 out of 5]

I received this as an ARC and couldn’t be more grateful. From the very first chapters, I was completely hooked. With multiple POVs and several twisty plotlines weaving together, it made for such a fun and addictive reading experience.

The only reason this didn’t quite land at five stars for me is that one element tied to a main character felt a little too hyper-focused at times. It popped up so often that it occasionally pulled me out of the story and started to drive me a bit bonkers. Think Freida McFadden’s book the coworker and the obsession with turtles… if you know, you know.

That small gripe aside, this was still a really enjoyable read and one I’d happily recommend to any thriller lover looking for a fast-paced, twist-filled story. Definitely worth picking up!!
