Something in the Water by Catherine Steadman

A #1 New York Times Bestseller and Reese’s Book Club Pick that has captivated over a million readers, Catherine Steadman’s debut novel is the kind of psychological thriller that makes you question everything—including yourself.

Erin and Mark seem to have it all: promising careers, passionate love, and a dream honeymoon in Bora Bora stretching before them. But when they discover something unexpected beneath the crystal blue waters during a scuba dive, their paradise transforms into something far more dangerous. One choice. One secret. And suddenly, the life they’ve built together begins to unravel in ways they never imagined.

Something in the Water is the perfect storm of suspense—the kind of book that keeps you turning pages long after you should have turned off the light. Steadman crafts a taut, propulsive narrative that explores the dark corners of human nature: What would you do to protect your future? How far would you go to preserve your dreams? And when does self-preservation become something more sinister?

“A psychological thriller that captivated me from page one,” raved Reese Witherspoon. “What unfolds makes for a wild, page-turning ride!” The New York Times praised how “Steadman keeps the suspense ratcheted up,” while the novel earned recognition as an ITW Thriller Award Finalist and landed on best-of-the-year lists from Glamour and Newsweek.

With piercing psychological insight and shocking twists, this is suspense fiction at its finest—perfect for fans of The Woman in the Window and Gone Girl.
