“Secret Keeper” by Brooke Montoya is a dark, twisty thriller where secrets aren’t just hidden—they test the limits of morality. Montoya pushes her characters into impossible choices, forcing them to weigh loyalty, truth, and survival. The pacing is sharp, the twists relentless, and the ethical gray areas make the story all the more gripping.

I couldn’t put this one down. It’s dark, twisty, and full of surprises—perfect for fans of psychological thrillers that keep you reading late into the night.

Audrey is in the business of keeping people's secrets and helping to work through them. Her new client shares a secret that she's not expecting. Can she keep it? Should she?

As Ian and Audrey's lives become more overlapped, they become buried under secrets they can't seem to get away from. Will those secrets be the end to the lives they know?

This twisted tale was a great read. The different POV gave a true insight to each character and what drives their actions. My first from this author and I'm excited to check out more.

Secret Keeper is a razor-sharp, addictive thriller. Montoya’s characters are messy, the secrets are explosive, and every reveal lands with a jolt. Dark secrets, dangerous choices, and a finale that delivers a stunning blow—this is the kind of book you clear your schedule for!

I WANTED to like this more, and the premise was intriguing, but ultimately, the execution and writing style fell flat for me

[Jenny Coyne · Rating 4 out of 5]

This thriller kept my attention through to the end! It has consistent pacing and lots of suspense. I only removed a star because I felt like the ending was a little anticlimactic.
