In the second installment of the Angelhart Investigations series by Allison Brennan, the private investigation team takes on a case that the police have already closed. A teenage boy named Elijah Martinez is said to have died from a drug overdose, but his mother doesn’t buy it—and neither does Margo Angelhart. What seems like a straightforward case turns out to be anything but.
As Margo starts digging, she quickly realizes things don’t add up. Elijah’s friends insist he never touched drugs, and when a teacher speaking out about the case dies suddenly, the situation takes a darker turn. The deeper she goes, the more she uncovers about an old drug operation tied to the school—one that might still be active.
Margo’s brother Jack, an ex-cop, tries pressing the police for answers but keeps hitting a wall. Now they have to wonder: is this an ongoing investigation, or is someone trying to bury the truth?
One thing’s clear—if they don’t act fast, more kids could end up in danger.
This book pulled me in right from the start—fast-paced, emotionally intense, and packed with suspense. Margo Angelhart is back, and she’s as sharp and determined as ever. When she takes on the case of Elijah Martinez, a teen whose death was ruled an overdose, what seems like a simple investigation quickly spirals into something far more dangerous.
I loved how the mystery unfolded. Each clue led deeper into a tangled web of corruption, secrets, and heartbreak, and just when I thought I had things figured out, the story surprised me again. There’s also just the right balance of family drama, with Margo’s complicated relationships adding depth to the tension.
This series really shines when it comes to character development and tightly woven plots. The stakes are high, the twists are great, and the pacing keeps you turning pages. If you're into gritty, emotional thrillers with strong female leads—think Lisa Gardner—you’ll enjoy this. I hope this series keeps going, because I’m already looking forward to the next case!

Favorite quote:
“People believe what they want to believe. They see no evil because they don't want to. But evil is out there.”

When Margo Angelhart is hired to find out the truth about Elijah Martinez's death she thinks it will be an easy solve. But the more she digs into the boys past the more she learns that things are quite as they seem.
Maybe his death wasn't an accident after all...

Don't Say a Word is one of those books that grabs you instantly and refuses to let go until the last page finds you. Margo is one tough cookie and she refuses to leave no stone unturned. She will do whatever it takes to get her answers for the families she helps and she goes above and beyond for Elijah's family.

This was an action-packed page-turner that had me on the edge of my seat the whole way through! I loved my time with Margo and her family and I cannot wait to see where their story takes us next! Highly recommend.

I requested an advanced copy of this title from the publisher and I am voluntarily leaving my honest and unbiased opinion.

I am an Allison Brennan fan for sure! Have to admit, I'm sad there's hasn't been more of the Kincaid clan, but the Angelhart's are winning me over. This is a nice, solid thriller. Maybe a little more on the predictable side, but the characters are well developed and enjoyable. I recommend!

Thank you to Net Galley and Harlequin Trade Publishing for gifting me this ARC in exchange for my honest review.

Fantastic mystery that keeps you guessing until the end. Just when you think you have it figured out there is a twist.
Margo is one tough lady. She never gives up. I’m looking forward to more development with the DEA agent.
Come along with the whole Angelhart family on a crazy adventure that will keep you coming back for more.

Allison Brennan DOES NOT MISS! Her writing takes readers on quite an adventure with Margo Angelhart. Elijah Martinez by all accounts was a good student and person. His mother cannot believe he would take drugs. Elijah was found dead in a park of an overdose - and after she meets with Margo and her family, they agree there are elements to examine. And then, another death occurs, and Margo knows they are related. As always, she speeds ahead, talking to more and more people whose stories aren't quite aligned and that adds to her belief that Elijah new something he shouldn't have. This book is fast paced, so incredibly twisty, and will keep you up well past your bedtime for just one more chapter. The family dynamics always add to the story - especially the relationship between Margo and her mom, Ava, who leads the agency. I absolutely loved this book!!! A huge thank you to NetGalley and Harlequin Trade Publishing | MIRA for an advanced reader of this book. The opinions expressed are my own.

The Angelhart family is one of my favorite book families. The dynamics of this family is very relatable and well written. I love how well they work together and always have each other's backs. The ending is always a surprise because you never see it coming with all the twists and turns.

I'm looking forward to the possible romance that was teased with Margot and Cal. That will definitely bring some fun interactions with the characters.

Another great book in the Angelhart Investigations Series. I love how the whole family works together as a whole to help their clients. Brennan does a great job in the development of the characters, especially Margo and her siblings. Margo is one strong female lead who likes to go on her own but is learning to lean on her family. Brennan has written a great story with plenty of action, twists, family drama, and so much more. Follow along with Margo has she investigates what happened to Elijah the night he died and did he really commit suicide. This was such an enjoyable and interesting read that I couldn’t put it down. I highly recommend this story and the series. Thank you Netgalley and Mira for the ARC in Exchange for an honest review.

I read the first two books in this series and this book is a great read as well. Allison Brennan knows how to knock it out of the park. Margo Angelhart and her family are all terrific and interesting characters. A family that loves one anotherand is semi dysfunctional at same time. Story line kept me rivitied as they worked together to solve the case. And Cal....cant wait to see what happens With him...

Fast-paced, emotional, and gripping—Don’t Say a Word pulls you right into the mystery. Margo Angelhart is a strong, determined investigator, and her latest case uncovers dark secrets, corruption, and deep personal stakes. Allison Brennan delivers twists, suspense, and heartfelt moments in this well-crafted thriller. Perfect for fans of Lisa Gardner and twisty investigative dramas.

This book is a perfect amount of mystery and just the right amount of family drama with all Margo's numerous family members . Love this series hope there is alot more books! ❤️ loved!

The police ruled Elijah Martinez’s death an accidental drug overdose, but the teen’s grieving mother isn’t convinced. With the case officially closed, Angelhart Investigations is the only one who can help her find the truth. Margo Angelhart’s sure this will be an easy solve, she’ll talk to Elijah’s friends and employer, retrace his steps, and figure out what happened in his final hours. Except none of his friends believe he did drugs, and the teacher who’s been vocal about the police mishandling the case turns up dead. Every thread Margo pulls leads back to a dangerous drug ring that once ran through the school! Great book and series! I thoroughly enjoyed reading this book! It had great suspense, murder, drugs, mystery, fantastic characters, action, intrigue and some shocking moments! The story was very interesting! I highly recommend reading this book and series! I can’t wait for more! Fantastic read! Thank you NetGalley and the publisher for sharing this book with me!
