Allison Brennan returns to her bestselling series with an edge-of-your-seat thriller that thrusts Quinn and Costa into the crosshairs of a sadistic serial killer.
Three newlywed couples have disappeared from an exclusive resort in Florida, only to turn up dead soon after. With the location and the similarities between the female victims as their only leads, it’s up to the FBI Mobile Response Team to catch a serial killer before anyone else ends up dead. And they have the perfect bait—Detective Kara Quinn, who bears an uncanny resemblance to the targeted women.
Undercover as newlyweds pretending to enjoy their honeymoon, Kara and FBI Agent Matt Costa set a flawless trap. When their plan works and they arrest the predator, Matt sends the rest of the team home so he and Kara can have the weekend for some much-needed R&R. But on Monday morning, the couple doesn’t show up to work, and the MRT learns they never checked out of their hotel.
As their team tries to find them, Matt and Kara learn the truth—the killer wasn’t acting alone. He had a partner who succeeded where he failed. Kidnapped and forced into a twisted escape room, they need to find a way out, because if they don’t escape, they’ll die.
New York Times and USA Today bestselling author Allison Brennan believes that life is too short to be bored, so she had five children and writes three books a year.
In 2019, Allison relocated from Northern California to Arizona with her family and assorted pets. She loves baseball, hiking, family game night, and (of course) reading.
RT Book Reviews called Allison “a master of suspense” and her books “haunting,” “mesmerizing,” “pulse-pounding” and “emotionally complex.” She's been nominated for many awards, and is a three time winner of the Reviewer's Choice award winner for RT Book Reviews as well as the Daphne du Maurier award. Most recently, she was nominated for Best Paperback Original by International Thriller Writers.
With over 45 books and dozens of short stories, Allison is writing multiple series and the occasional stand alone thriller. Her most recent book out now is THE MISSING WITNESS, part of the Quinn & Costa series. In June Allison is launching a new Phoenix-set series about a family of private investigators starting with YOU'LL NEVER FIND ME.

This is an entertaining, well-written, fast paced police procedural. It has a strong and capable female protagonist, an engaging male protagonist, supportive secondary characters, murder, mystery, suspense, twists and turns, a touch of romance, and a satisfying conclusion. This is the seventh entry in Ms. Brennan's outstanding Quinn & Costa series, and my favorite so far. It can be read and enjoyed as a standalone. I listened to the audiobook, and the narrator, Ms. Suzanne T. Fortin, does a fantastic job voicing the characters.
The Mobile Response Team is back. This time trying to catch a serial killer of newlywed couples at a fancy Florida resort before they strike again. Kara and Matt go undercover as newlyweds. When they think they have caught the killer, everyone heads home except for Matt and Kara. They stay to enjoy resort for a night not on the job.
But when they don’t show up back in Quantico and no one can get in contact with them, the rest of the team becomes concerned. Where could Matt and Kara have gone, leaving everything behind. Did they catch the right killer?
As the team works to find them, Matt and Kara are in for the fight of their lives. Just who is the Mephistophelian (new word for me from the book!!) behind their disappearance and is it related to the newlyweds resort killer?
This might be my favorite of the series!! The rest of the team has to work without their leader because Matt is no where to be found. It’s interesting to see how that part of the story plays out. The terror and uncertainty Matt and Kara face, it’s tense. It’s a rescue mission for the MRT to find Matt and Kara. It’s a survival mission for Matt and Kara to stay alive in hopes of being rescued. Does everyone make it out alive? Is the same person responsible for all of it?
I highly recommend this entire series. While not completely necessary to have read the previous books, it is really helpful for character development and relationships, plus, they are really good!!
A huge thank you to NetGalley and Harlequin Trade Publishing for the arc of this book. All opinions are my own. Expected release date January 27, 2026

2/5/26: now listening to the audiobook version!! 😊. My review disappeared when I changed it to ‘reading’, so I switched it back to read, but it chanted my review posting date to today, hence adding this note🤪. Another just for my reference note again.
the setup… The Mobile Response Team’s latest case is in Jacksonville, Florida at the exclusive Sapphire Shoals Spa Resort where three newlywed couples stayed and were later found dead. FBI Agent Matt Costa (also the team’s leader) and Detective Kara Quinn, who has a striking resemblance to the victims, go undercover as newlyweds to bait and catch the killer. When they successfully capture Garrett Reid, Matt and Kara decide to stay the rest of the weekend and get some much needed private time. But when they both fail to show up for meetings on that Monday, it becomes clear that not only are they missing but Garrett seems to have had a partner. Meanwhile, Matt and Kara awaken from a drugged stupor to a nightmare…they’re in an unknown, remote and dangerous location and fighting to stay alive.
the heart of the story… Wow! Just…wow! Without giving anything away, Matt and Kara are facing one of their biggest challenges ever as the place is laden with lethal boobytraps. I felt like I was holding my breath as it was a race against time (no food or water) while the team desperately tried to figure out where they were and the identity of the partner in crime.
the narration… Suzanne Fortin delivered a fine piece of storytelling, keeping me enthralled and giving distinctive voices where it mattered. I hung on her every word.
the bottom line… Love the series, love the team but this was something more. Every member rose to the moment and did what they do best in their respective roles. The procedurals were superb and it was exciting to follow along as they unraveled the case. Matt & Kara are highly skilled but were physically taxed and brought to the brink. Brennan is a favorite but this story far, far surpassed my expectations.
OMG! OMG!OMG! This book just cements Allison Brennan as THE BEST!
LAPD Detective Kara Quinn and FBI Special Agent Matt Costa are undercover at a Florida resort where three other couples have been kidnapped and murdered. They get their man, but there are problems with the case. No matter, the FBI Mobile Response Team was just meant to apprehend a suspect. It's up to the locals to make the case. With the MRT heading back to DC, Kara and Matt take the weekend as some much needed R&R. When they fail to show up on Monday, the MRT is more than concerned and immediately launch a search for their missing team members.
When Kera and Matt regain consciousness in an abandoned factory, they know that their perp didn't act alone. What follows is both chilling and a race against time and time is not on their side.
My thanks to the Publisher and the Author for providing a complimentary digital Advanced Reader Copy (ARC) of this novel via NetGalley. This is my fair, honest and personal review. All opinions are mine alone and were not biased in any way.
While this is book 7 in a series, it works as a standalone. I hadn't read the other books and I felt like I was able to catch on to our characters quickly. In fact, I want to go back and read the other books in the series now.
The procedural portion of this book is very well done. In fact, I liked it a bit more than the thriller part. For the thriller part, there was a bit of disbelief that the character in question had the skills and knowledge to do everything they did. I just kept...not believing.
The book is intense and, as things ratchet up, the reader is absolutely on edge.
Allison Brennan is one of my top favorite writers! I've read all the books about Lucy Kincaid. I liked the earlier books better, Lucy was starting to complain too much!
I've read this series from the beginning. There's always a lot going on in these books! If you have read all the books from the beginning you would know who Catherine, Michael, Jim and the others are...
In this story Matt and Kara pretend to be on honeymoon at a resort. Three other couples on honeymoon had disappeared from the resort and been found dead!
They soon catch a man in the act but they don't really have any evidence against him. He says that he had just seen them on the floor and gone in to make sure they were OK...
The rest of the Mobile FBI team go home while Matt and Kara stay since the room is paid for.
They are supposed to be at work on Monday. When they don't show up the others soon find out that Matt and Kara have been taken! Had they arrested the wrong guy!?
This was a great book! I listened to the book that I borrowed from hoopla.
I had a problem with a medical fact. I used to work with infectious disease patients and later in the ER. If a cut is really dirty you don't stitch it! That could lead to a serious infection!
It’s cat chases mouse, or maybe the mouse is chasing the cat…
Matt and Kara are investigating a serial killer of couples. But is the man in custody really their man? Now Matt and Kara have gone missing and the rest of the team need to find them. Hoping against all hope that they got this right.
But everything is slipping through their hands and now they can’t find their agents.
🎧: this audio was a fantastic listen. I could listen to this narrations forever if I had to. Haha. Just made for an excellent listen. Def recommend this audio for this book.
Bam! Loved this one. Such a fun read. I loved the chapters with Matt and Kara. But the investigation side was also fun to read.
Kara and Matt end up in an escape room type of room - only there’s no puzzles. But these chapters were so fun. The investigation side was just as compelling.
A complex mystery with lots of moving parts - a solid read. Enjoyed.
IM SHOCKED i havent heard of this author before. This was really good. If you like police procedurals you'll love this. This is the latest book from this series and I was able to understand everything without reading the other books first. But because I havent read the other books I was not able to connect with the characters as much. Im so excited to read the rest of this series in order.
I cannot recommend this book highly enough! Yes it’s a series but you can totally read this as a standalone! And talk about a wild ride of a story!!! I literally can’t tell you anything so I don’t spoil the craziness!
I accidentally grabbed this ALC (seriously fat fingers), but I’m actually glad I did—even though police procedurals aren’t usually my favorite subgenre.
This one is fluffy in the sense that you don’t have to think too hard. You’re along for the ride, enjoying how all the pieces fit together rather than puzzling out the culprit. Why? Because it’s extremely predictable. As soon as the culprit is introduced, you know it. It’s not explicitly stated, but the presentation might as well be wearing a name tag.
That said, I still enjoyed the experience despite the lack of real suspense or any genuine fear that our main characters were in danger. Honestly, that’s probably why I don’t often gravitate toward this type of book—you can usually tell from the description alone that the recurring cast will survive. The fun, such as it is, comes from seeing how they get there.
This is the seventh book in the author’s Quinn and Costa series. I haven’t read any of the previous installments, but they seem to be well-liked, and I don’t expect this one to break that streak.
My main issue? The narration.
Normally, audiobooks elevate my experience—but apparently not everything can be saved by audio magic. The narrator, Suzanne T. Fortin, speaks painfully slowly at 1x speed, and her characterizations just didn’t land for me. None of the characters sounded remotely like law enforcement, and some of the phrasing and vocal choices were… baffling. The only way I could tolerate it was by bumping the speed up to 2x, where it became merely acceptable instead of distracting.
To be clear, her natural voice is perfectly fine—it just wasn’t a good fit here, and it definitely dampened my enjoyment. I suspect I would have liked this book much more in print.
This releases in January 2026, and I do recommend it—just do yourself a favor and opt for the ebook or physical copy if you have the choice. Your ears will thank you.
I was fortunate to receive a complimentary ALC from Harlequin Audio via NetGalley, which gave me the opportunity to share my voluntary thoughts.
How I Rate Because I mostly read ARCs, I focus on how I think fellow readers with similar tastes will respond. I sometimes round up or down based on pacing, prose, or overall impact, and I try to keep my personal preferences from weighing too heavily.
⭐️ 1 Star – Finished, but not for me as it has way too many issues; I never DNF ARCs but would have had it not been one. ⭐️⭐️ 2 Stars – Struggled due to writing, content, or editing issues. ⭐️⭐️⭐️ 3 Stars – Decent read with untapped potential; recommend with some reservations. ⭐️⭐️⭐️⭐️ 4 Stars – Really enjoyed it and would recommend for several reasons. ⭐️⭐️⭐️⭐️⭐️ 5 Stars – Exceptional; lingers in my mind well after reading. A story I’d gladly revisit.
This was certainly bingeable and kept my attention. It’s also unique- a fun house of horrors? {insert full body shiver}. It got a bit long and drawn out but overall a tense and gripping read! I’ve enjoyed this series and can’t wait for the next book!
I’ve listened to every book in the Quinn & Costa series and feel that while this one was probably the most outlandish in terms of believable plots it also felt the most connected that this team of FBI agents have been within the story. It was pretty fast paced so much so that when the opening chapter started I thought I had skipped ahead in the book. It starts off right away into the action and hardly ever lets up.
There’s something about how the character Cara Quinn is written that I really like. She’s tough and fearless but also has great instincts for the human spirit. I like her pairing with Matt Costa and their chemistry. I like that he sees her as capable and strong.
I will say this isn’t my favorite of their stories but it’s definitely a good one.
2.5 but rounded down for goodreads. I had a few problems with this book. -the dialogue was stilted -lack of intrigue/mystery -far too many POVs -police procedural
Thank you though to the hive for letting me listen to this audiobook!!
I’ve read the Quinn & Costa series from the very first book, The Third to Die – albeit out of order. Nevertheless, I’ve found each and every book in the series to be compelling and absolutely un-put-downable in the reading – even if at the end I find myself wondering WTF happened along the way.
This book turned out to be one of THOSE kinds of reads.
The story begins at what feels like an ending. The FBI’s Mobile Response Team – and the local law enforcement in Flagler County, Florida (just south of St. Augustine) – are sure that they’ve just caught a serial killer in the act. Which they sorta/kinda did – just not the act that would have closed the case.
Someone has been killing newlywed couples on their honeymoons at a ritzy resort, so the FBI set Matt Costa and Kara Quinn up as a newlywed couple to capture the killer. But the team staking out the undercover agents jumped the gun on the takedown because one of them thought they saw a gun.
So instead of a slam-dunk arrest AFTER the killer had them trussed up and on the way to his vehicle they caught him after the pair had been drugged but before they’d been restrained. The perp’s explanation of oh-so-many coincidences is tissue-paper thin – but there’s really nothing that can’t be explained – however badly – and no physical evidence to tie him to anything at all.
He’s cool, he’s smart, he’s clever – and he gets out on bail.
But while their suspect is in jail, Matt and Kara take an extra day at the resort for themselves. As vacation. They’re sure the murderer is in custody, and the team’s crack profiler is certain the killer was working alone.
He wasn’t. A mistake that threatens to cost Matt Costa and Kara Quinn their lives. Unless, together, they can make their way out of a brilliantly engineered but diabolically twisted factory turned vast and deadly escape room. They had hoped to find the place where the previous deaths had occurred – but not from inside the exact, same trap.
Escape Rating B+: This is a hugely mixed feelings kind of review, and I’m a bit bummed because I was expecting my second “Allison” of the week to be every bit as good as the first.
Don’t get me wrong, the story is a wild thrill-a-minute ride from beginning to end. It turned out to be a single-evening read that I couldn’t put down for a second. The pace is incredibly fast, the danger is ramped up to eleven from almost the first page and the opening, where the cops are all sure this is nailed and those nails get taken out one screeching pull at a time invests the reader in the story immediately.
Which is the point where, well, the point of view fragments into separate strands and things get wild and crazy but also go off the rails – including, at some points, actual rails.
For the rest of the story there are three main-ish perspectives. The one with the highest and craziest danger quotient is that of Costa and Quinn. They’ve been drugged, kidnapped, and dropped inside a remote house-of-horrors escape-room factory where every step is booby trapped and every door leads to more ways to die.
Their absence leads to the second thread, which is, of course, the mobilization of their team AND seemingly most of the resources of the entire FBI in finding them.
The third thread follows the actions of the real villain in this story. And this is where things fell more than a bit apart for this reader. Call it “villain fail”. The true villain of the story read very much like a cartoon supervillain. I want to say Harley Quinn, making the terrifying escape room factory into Arkham Asylum, but Harley Quinn was actually a whole lot smarter than this…person…although the resemblance to Arkham Asylum is still right on the nose.
The real villain in this was a whiny, bitchy, narcissist who seems to have been more lucky than smart. She was honestly kind of boring. Horrifying, crazy and even downright evil, but more of a caricature than a character. The person that the cops believed was the sole killer was a more interesting, and more nuanced, potential villain. Not that he wasn’t just as big a criminal in the end, but he wasn’t a villain.
Thrillers like this one where we see inside the killer’s head either creep me right the fuck out or trip my willing suspension of disbelief. This one did the second even though it was trying to do the first. She was just over the top and cartoonish even though she wasn’t a cartoon supervillain – no matter how much she wanted to be.
Of the three sides to the story, Matt Costa and Kara Quinn’s one-step-forward, one drop downward trip through the nightmare factory both propelled the story forward and provided the ticking clock that kept this reader on the edge of her seat.
The frantic investigation being carried out by their team added in the ‘competence porn’ element that I read this series for. They were all good at their jobs – at least once that mistaken profiler admitted her mistake. At the same time, this part of the story showcased the tight teamwork of the Mobile Response Team as well as displaying just how integral Quinn and Costa both are to their success.
While on my third hand, I’d have liked this one a hell of a lot better if we didn’t have a peek into the villain’s head – even if, thank goodness, it’s not a direct first-person perspective. It was kind of expected that she was a self-centered narcissistic psychopath, but the one-note whininess was just over the top – and not in a good way.
Which leads back to my mixed feelings. That B rating is for the villain fail. The plus sign attached to it is for the compulsive read. This entry in the series was exactly like sticking my hand in a bag of potato chips – once I started I couldn’t stop sticking my mind back into the bag.
So I’ll be back for the next book in the Quinn & Costa series, both to see how they’ve recovered from their truly unfortunate adventure in this one – AND to see if they have a more interesting villain to catch the next time around!
Three newlywed couples have disappeared from an exclusive resort in Florida, only to turn up dead soon after. With little to go on, the FBI Mobile Response Team has to resort to risky tactics to catch the killer. with Detective Kara Quinn bearing a striking resemblance to the women, they set her and Matt up as a newlywed couple, as bait. Undercover enjoy their time together, and set the trap. It works, but the rest of the team jump in early, and the killer is arrested, but for how long will he remain in custody. When they are ready to check out, Matt and Kara are missing. They realize that the killer wasn't working alone. They move into high gear to find them before they end up dead. Meanwhile, we follow them trapped in a factory that is full of booby traps, and every step could be their last.
All I can say is WOW! This is the most tense, twisty and scary story I've read in this series. With their lives on the line, Matt and Kara must work together, as well as support one another to free themselves from this situation. The team is frantic, working against time to find the accomplice. I don't want to give anything else away, but will say that I was on the edge of my seat all they way through this one. I like seeing how well the Mobile Response Team works together, the specialists that they have access to, and how much they care about one another. The reader learns who the partner is, but as the story progresses, it is Matt's and Kara's predicament that is front and center. an excellent addition to this series. The audiobook was excellently narrated by Suzanne T. Fortin. She is the voice of this series and gives voice to the story. I highly recommend this book and series in whatever format you prefer.
At an exclusive resort in Florida, a serial killer appears to be targeting newlyweds. The similarities among all the female victims are unmistakable. The FBI is on the case and sends Detectives Kara and Matt undercover to pose as newlyweds. Kara bears a strong resemblance to the female victims, and their plan seems to work effortlessly. After the suspect is arrested, Kara and Matt decide to spend the rest of the weekend at the resort for some much-needed rest and relaxation. Instead, they experience anything but that. It seems they either arrested the wrong man or he has an accomplice, because now Matt and Kara find themselves drugged, kidnapped, and trapped in a survival mission of their own.
What I loved most about this book was the relentless tension and the twists that kept coming right up until the very end. The ending did not disappoint. I was captivated from the very beginning and remained engaged until the final page. The escape room elements had me on the edge of my seat, fingers crossed that everything would work out for Matt and Kara. With a compelling mix of police procedural, locked-room mystery, escape room challenges, and a fight for survival, I thoroughly enjoyed this book.
The Quinn and Costa Series has become one of my favorites. With each new installment, I love it even more. The latest, does not disappoint. This one had some really heart stopping moments. If you are not reading this series, start today!
The latest installment finds The Mobile Response Team arresting a maintenance employee at a Florida resort. There are some unanswered questions after the arrest. The undercover operation had Matt and Kara posing as a married couple. After they wrapped the case, they took a few days off. Everything seemed okay until they didn’t show up to work on Monday.
Allison Brennan has crafted a superb thriller/mystery here. Matt and Kara are fighting for their lives to escape a trap, while the MRT tries to find them before time runs out. There are so many twists and turns, and I don’t want to say more - you will be catching your breath throughout this book.
And the ending? Wow!
Now the wait begins for the next book. I cannot wait to see what happens next. Thank you to NetGalley, Harlequin Trade Publishing, and Hanover Square Press for the opportunity to read this one early! It is fantastic! This one is out on January 27th - start this series today!
Quinn and Costa are back in this locked room installment of their series. They are undercover trying to lure a killer of honeymooners, and just when they’ve got a suspect in custody, they become part of the case. They’re kidnapped and brought to a booby trapped warehouse. Can the rest of the Mobile Response Team find them in time? This book was an edge of your seat, page turner as Brennan’s books usually are. Readers get the dialogue and the camaraderie that they’re used to from this series, and they get a deeper look into Quinn and Costa’s relationship.
The only downside to all of the dialogue is that the audiobook narrator couldn’t quite keep up with all of the characters to make them sound different. Conversations between characters were hard to follow because it was hard to tell who was speaking. Readers may want to stick to reading this one and skip the audio.
I voluntarily read and reviewed advanced ebook and audiobook copies of this title from NetGalley. All thoughts and opinions are my own.
Make It Out Alive pulled me in right from the start and kept the tension high, even though it slowed a bit for me in the middle. I’ve read a few of Allison Brennan’s other thrillers and was excited to pick this one up, and it didn’t disappoint. Even though this is part of an interconnected series following an FBI Mobile Response Team, I had no trouble jumping in and getting a feel for the characters. The narration was well done and added to the tension. The stakes felt high, and I really enjoyed the mix of suspenseful escape room elements with the procedural side of the investigation.
3.5 rounded up to 4⭐️
Thank you to Harlequin Trade Publishing and Harlequin Audio for the ARC and ALC in exchange for my honest review.
This was another fast, high-stakes read that pulled me right back into Quinn and Costa’s world. I liked how the story picks up after the undercover newlywed setup from the previous book and immediately raises the stakes instead of resetting anything. Once things shift into the escape-room situation, the pacing takes off and I flew through it because I genuinely needed to know how they were getting out. The danger felt real, the twists kept coming, and I appreciate how Allison Brennan keeps finding new ways to push these characters without it feeling stale. A few moments required some suspension of disbelief, but overall this was an intense, addictive thriller that reminded me why I keep coming back to this series!
Make it Out Alive is the seventh book in the Quinn & Acosta series. Matt and Kara are at the end of a much needed vacation when they are abducted and wake up in a deadly escape house scenario. Their team must race against time to find out happened to them. I have to say that I really enjoyed this one much better than the previous book. We get much more of Matt and Kara together. And honestly, they are why I keep reading this series. I loved their interactions and how they worked together to get out of their situation. I also really loved how the team has really become a cohesive unit by this book. The overall msytery was good. There were a lot of hold your breath moments. I'm looking forward to the next book in the series!
I have made it to the end of the series and I’m so sad. I have fallen in love with all the main characters. What I loved about each of the books is we were dealing with something completely different in each one. If you read the acknowledgments at the end you know Allison Brennan does her research, which I think brings the story more to life. When I first started reading her books I actually started with 4 because I didn’t know it was a series. I ended up loving it so much, that I was happy to read the rest of them. Every book keeps you on your toes in the best way possible. I look forward to when the 8th book comes out!
This was one of my favorite books in the series. Kara and Matt were forced into unfamiliar territory. It was strange, but interesting to see them as victims. Their captor was insane. Her motive felt silly, but it kept it entertaining. The race to save Kara, Matt, and the other people that had been abducted created a good amount of tension in the storyline. The final outcome was twisted, but satisfying. I’m hoping that this is the series finale. It’s a good way to end it.
Our next movie!! Oh what a thriller-Serial Killers?, FBI, murders?, our heroes-Kara and Matt are missing, team is working overtime, beautiful women, THE GAME! Oh readers, this is one outstanding plot, characters and of course the twists and turns…ENJOY T
Allison Brennan did it again. This book was fabulous. Lots of twists and turns. It gave all of the characters of the Mobile Response Team a chance to grow and shine. I loved it.
