Donlea has become an autobuy author for me. I've never been disappointed by a book of his and Guess Again has become my new favorite of his. If you like fast paced thrillers with less than perfect heroes this book is for you. If you are a fan of cold cases this book is for you.

It's been ten years since Callie disappeared and her body has never been found and no clue on who took her. Ethan, a ex detective turned doctor has been tasked by his old partner to take a look at the case. Can Ethan solve the case that no one has been able to for 10 years? Eventually Ethan learns there is someone out there that still believes there are secrets worth killing for.

I give this 5 stars! I loved it! Release date 7/29/25!

First of all thank you for allowing me to read an advanced copy! What a book!! I didn’t see the multiple plot twists coming at all. This book kept me engaged and anxious, wondering what would happen next.

⭐️⭐️⭐️⭐️✨- 4.25 stars.
Charlie Donlea does it again! 🔥 Guess Again is another solid thriller that kept me hooked from start to finish. He has such a talent for building suspense and weaving in just enough twists to keep you turning the pages.

Charlie Donlea has become one of my favorite authors. I find his thrillers to be page turners, regardless of the storyline, so I was excited to get an early copy of his latest, “Guess Again.”

Set in Wisconsin, Ethan Hall’s a former detective. He retired to get away from the horrors he encountered regularly in his work and went to medical school. Now an ER doctor, Ethan enjoys the life he’s built. Unfortunately, his former partner, Pete Kramer, asks him to come out of retirement and investigate a 10 year old cold case. Pete has been diagnosed with ALS and he wants the case to be solved before he dies. He feels Ethan is the best person for the investigation because Ethan retired with a 100% solve rate.

Ethan ultimately agrees to look into the cold case involving the disappearance of Callie Jones. She was a 17 year old high school star volleyball player who disappeared one July night. As Ethan begins to look into Callie’s disappearance, he gets pulled into another case. There’s a female who disappeared a month prior and it’s somehow related to Callie’s case, but Ethan’s trying to figure out why.

There were several narrators in this book. The reader heard from Ethan, an unnamed female, and the man who killed Ethan’s father over 30 years ago. This was a solid book from the author, but it wasn’t my favorite of his. I was not a fan of the ending, but to say more would reveal spoilers. I may also be in the minority with how I felt about the ending.

Overall, I recommend this book. Thank you to the publisher and NetGalley for my ARC.

I really really liked this book, Charlie has a great writing style and gets to the point well.

However, there are so many characters and storylines that it just became so busy and I struggled at points to figure out who I was reading about and what timeline.

Overall 3.5 rating.

Ok Charlie Donlea. Why are you doing this to me? I started Guess Again and couldn't stop until I finished it! I had things to do today...but obviously reading took their place. Guess Again is Donlea's latest work, and may just be the best one yet. Each new novel is just improving on the thriller formula that Donlea has mastered. I really enjoyed the intricate plotting that shows throughout this mystery about the 10 year anniversary of a teenage girl's disappearance and how an imprisoned killer is possibly connected. I highly recommend this one.

A big thank you to NetGalley and Kensington Publishing for graciously providing an ARC in exchange for an honest review.

This book was a solid 3.5 stars for me; I didn't want to put the book down, I felt compelled to keep reading and find out what happened. However, I thought there were a lot of characters and different storylines going on; sometimes the book jumped around and it was hard to keep everything straight. I also felt like this was pretty depressing. I like suspense/thriller books when there's the thrill of the chase: you don't know how, but you know the good guy is going to catch the bad guy. In Guess Again I felt like the bad guy kept winning. I agree with other reviews that suggest that there will be a sequel, it seems like it's perfectly setup for one at the end of the book.

Thanks to NetGalley and the publisher for providing an ARC for review.

FAB-U-LOUS!!! Literally could not put this book down!

Twisty, fast-paced, and totally addictive. Guess Again follows a former detective drawn back into a cold case involving a missing girl—and nothing is what it seems. With multiple timelines, creepy twists, and a few jaw-dropping reveals, this one keeps you guessing until the very last page.

Rating: 4.5/5 – Sharp, suspenseful, and full of surprises. Perfect for fans of smar

Ready for a wild ride through a dark and twisted criminal investigation?

GUESS AGAIN opens with a hook that ensures you’ll want to know what happens next.

We have a likable main character who is pulled back into a decade-old investigation, and he’s not happy about it. The story is told via past and present timelines, with short chapters and not much breathing space.

The ending gives us closure, while also allowing for a possible sequel.

*Thanks to Kensington Books for the free copy!*

This is my least favorite of Charlie’s books. I didn’t find this that hard to figure out and did so before the book was halfway over. This is one you’ll need to read a physical copy of, I think audio will get incredibly confusing because sometimes chapters are in the same day, a week ahead, 10 years behind, or a year ahead. Things happen with no explanation and you’re really essentially teleported into scenes where you find yourself going back thinking you missed something. There’s a lot of repetitive language, characters changing titles, and things that are just not going to happen in the real world with cops involved. That being said this is incredibly easy to binge,I think I finished it in under 4 hours.

Guess Again had me hooked from page one. When former detective Ethan Hall is pulled back into a cold case, what starts as a search for closure quickly spirals into something darker and far more personal. The pacing is sharp, the twists hit hard, and Donlea nails the suspense. Definitely a must read!

Ah, Charlie Donlea, you should be sitting with only 3 Stars on the horizon. Plenty of potholes lining this one. But ya got me with the New Glarus Spotted Cow Beer. Let's chat this one up.

Ethan Hall is a two-fer. He started out as a detective in specialized cases for Wisconsin. After ten years, the burnout was significant. At thirty-six years old, Ethan tosses that career and went to medical school. He's now a superb ER doctor.

But you can't always outrun your past. Veteran detective Pete Kramer has come calling. He's been working on a ten year old case. It just so happens to be the missing daughter of the present governor. Ethan gets talked into pursuing this case while working his ER shift.

Callie Jones had the world on a silver tray. She'd been accepted into medical school from a prestigious university. She and her friends were celebrating in Summer style. But the last time that anyone saw Callie was when she was driving her father's boat away from an island on the lake. No clues and no body were ever found.

Meantime, a serial killer has been busy depositing bodies along Lake Michigan. He leaves his special markings. Could Callie have been one of his victims? Stay tuned. This one is tied up in giant knots.

Charlie Donlea writes like his hair is on fire. And those flames will always burn in your memory. But Guess Again took more literary liberties than a squirrel stashing nuts away for the winter. Ya grabbed me, Charlie, until that vicious twist came knockin'. It was unbelievable with a capital U. Eye rolling music, please. But all is forgiven as we sniff the air for a possible series in the wind. Will even Evan be able to pull this one off? I'm definitely locked in for that......definitely.

I received a copy of this book through NetGalley for an honest review. My thanks to Kensington Books and to the talented Charlie Donlea for the opportunity.

What an utterly good story. What a great thriller. All the 5 stars are worth it!
It all comes together in a master plotted end. I read this book in two days and loved it.
It is an easy written story about a detective which became a doctor. To get away from all the horrible things only to get sucked back jn again. There are a lot of unexpected twists, with a biggie at the end. This is a fast-paced story which is written in a movie-style.
I think the ultimate summer story!

If I could give this more than five stars I would!!! My jaw dropped I stayed up way to late reading since I couldn’t put it down. I loved it! A summer must read!

Rating: 5 ★ 

A decade after high school volleyball star Callie Jones vanished without a trace from her small Wisconsin lake town, her case remains unsolved and the community still haunted. Ethan Hall, once a detective in the child crimes unit and now an ER doctor, is reluctantly pulled back into his old world when his former partner—now terminally ill—asks him to reopen the investigation for the sake of the family’s closure. As word spreads through Cherryview, hope is reignited. But in the middle of a brutal summer, Ethan quickly realizes that solving the case will take more than revisiting the past—it will require digging deep, taking risks, and confronting painful truths, including a disturbing link to his own past. The closer he gets to the truth, the more dangerous the game becomes.

Charlie Donlea continues to prove why he’s one of the best in the thriller genre. Guess Again is a fast-paced, twist-filled mystery that grabbed my attention right from the start and didn’t let go. The story follows Ethan Hall, a former detective turned ER doctor, who is pulled back into his old life when asked to solve a cold case involving the missing daughter of Wisconsin’s newly elected governor. With a 100% solve rate in his former career and a deeply personal connection to the case, Ethan’s return to investigating quickly becomes more than he bargained for.

The plot is layered and intricate, full of red herrings and shocking twists—some I saw coming, but many completely blindsided me. Donlea does a great job weaving past and present timelines while maintaining the suspense throughout. I appreciated the short chapters and fast pacing, which made this a super quick read despite its complexity. There are a lot of characters to keep track of, and while not all of them felt deeply developed, the sheer momentum of the story kept me engaged.

The final twist is one of the most memorable I’ve read in a while—Donlea really leans into the title here. Just when you think you’ve got it figured out… guess again. The ending was intense and left the door wide open for a possible sequel, which I’m definitely hoping for.

If you’re into cold cases, serial killers, or thrillers with a psychological edge and a touch of emotional depth, Guess Again should be on your list. It’s easily one of the most compelling thrillers I’ve read this year.

Favorite Quote:
"she found a bench near the water, took a seat, and pretended to scroll through her phone while she looked for anyone who might have followed her. She saw no one. Finally, she stepped back onto the walking path and made her way to a little free library. The stand looked like a large birdhouse.. The triangular structure was perched on an oak pole and housed a variety of free books for anyone to take."

Thank you so much Kensington Books for the gifted ARC!

4.5 stars

WOW- Charlie always finds a way to blow my mind, but this is definitely his best one yet!

I don't know he managed to take so many different timelines and perspectives and weave one of the wildest unsolved murder mystery stories I've ever read, but he absolutely NAILED every single detail!

If you love short chapters (most two to three pages), multiple timelines, insane characters you won't soon forget, then this one is definitely for you!

I feel like this could have been so confusing because there were SO many moving parts, but somehow he made it all so easy to follow and understand. That is not easily accomplished!

I can't wait to see what he accomplishes next!

This was the surprise of the week for me and what a pleasant surprise it was. Another "new to me" author and so I went into this ARC with absolutely NO expectations.

I love most genres and tend to hop around from one to the other fairly regularly, but had never even heard of Mr. Donlea before. I will say that once I started this book, I could NOT put it down. The pacing on this book is excellent, with short powerful chapters that found a way to grab you early on and pull you into the story.

This story is told with multiple POV's and also has different timelines. The basic plot surrounds the disappearance of high school senior Callie Jones 10 years ago in a case that is still unsolved. The case is reopened by the victim's father when he is elected as the new Govenor. In another odd scenario, we meet the MMC Ethan Hall who was a former detective turned ER doctor when he left law enforcement to escape the horrors of the children's crime division.

The story is compelling, unfolding as Ethan begins to investigate the case, with snippets of the actual events in the past thrown in intermittently. I can usually follow along and figure out the "killer" in advance in most books, but I will be the first to say that I do not think anybody is going to figure this one out. The minute you think you understand what is happening, something changes. I was seriously hooked, trying to keep reading to figure out WHAT THE HECK was going on.

There are twists upon twists, but they are NOT thrown in like so many of today's books are -just to get a reaction, or a twist thrown in that completely goes against the rhythm of the story. These crazy events end up tying up all of the loose strings that have been thrown out during the story, somehow making things make sense, yet never in any ways that you were thinking.

Seriously, this book made my jaw actually drop open, and then had the gall to leave an open-ended ending, which means.....yep, you guessed it....there looks like there is going to be a book 2 in this series. And for once, I'm not even annoyed. I just think that next time I am going to go in expecting some serious drama because THIS bad guy, well, he is REALLY bad.....

Thank you to NetGalley and Kensington Publishing for the opportunity to read and review this ARC. This book will be out for publication on July 29, 2025.
