Quick Verdict
I'd been putting off Something in the Water for months—thrillers set in paradise rarely deliver anything original. Catherine Steadman's Reese's Book Club debut changed my mind within the first three chapters. The premise alone earns its keep: an underwater discovery that should stay buried, a couple already fracturing under the surface, and a narrator whose voice pulls you in like a riptide. This is a tight, propulsive thriller that rewards patient readers. 4.2/5.
What Is Something in the Water?
Something in the Water is Catherine Steadman's debut novel—a psychological thriller that landed on Reese Witherspoon's book club radar and never quite let go. Published by Ballantine Books, the story centres on Elisabeth and Mark, newlyweds heading to Mokoia Island in New Zealand for a honeymoon that feels like the world dropping away. He's a corporate lawyer with a polished exterior; she's a documentary filmmaker still grappling with a family tragedy that cost her career. Within 48 hours of arrival, their carefully constructed lives begin to crack.

The hook hits fast: while scuba diving near their resort, Elisabeth and Mark stumble across something they shouldn't have seen—a scene frozen underwater that pulls them into a moral maze with no clean exits. What follows is less a whodunit and more a how-will-they-survive. Steadman writes Elisabeth as an unreliable narrator from the start, and that ambiguity is the engine driving the whole book. You trust her instincts even when you can't trust her version of events.

Hands-On Review
I cracked this open on a Friday evening with low expectations—another tropical thriller promising paradise and delivering corpses, probably. By page 40 I was already calculating whether I could skip Saturday plans to finish it. What caught me off guard wasn't the mystery itself but how small the cast is. There's essentially one couple, a handful of resort staff, and a growing sense of claustrophobia that mirrors Elisabeth's deteriorating mental state. That's a smart structural choice. You're never quite sure who's safe.
The writing won't win literary prizes, but Steadman's background as an actress shows in her dialogue and pacing. Elisabeth's voice is sardonic, occasionally mean, and compulsively readable. I found myself underlining passages not for their prose but because she'd nailed a specific emotional frequency—the kind of passive-aggressive politeness that masks real fear. The honeymoon romance between Elisabeth and Mark is deliberately thin at the start, which is the point: we learn who they really are together through crisis, and by the midpoint you'll have firm opinions about both of them.
What surprised me was how the thriller mechanics hold up. Steadman doesn't cheat. The clues are all there if you're paying attention. The twist lands harder because of how carefully the false trail is laid. I went back and re-read chapter 11 after finishing—it all clicks. The audiobook, which I listened to on a road trip, is genuinely excellent. Steadman performing her own work has that same quality as Stephen King reading his: you hear the beats she intended, the pauses she wrote in. Two thumbs up if you prefer audiobooks.
Who Should Buy It?
- Reese's Book Club fans who want something darker and more propulsive than the Club's literary fiction picks
- Audiobook listeners – Steadman's narration elevates an already strong thriller experience
- Beach read seekers who want substance under the sunshine—a thriller that earns its twists
- Readers who love unreliable narrators – Elisabeth is sharp, unreliable, and impossible to look away from
Skip this if you prefer your thrillers with a clear moral centre, solved police cases, or zero ambiguity in the ending. Something in the Water trusts you to sit with discomfort.
Alternatives Worth Considering
- The Girl on the Train by Paula Hawkins – if you want a more established psychological thriller with unreliable narration and a completed trilogy
- Behind Closed Doors by B.A. Paris – for a tighter, shorter domestic thriller with similar moral ambiguity
- The Silent Patient by Alex Michaelides – if the Reese's Book Club connection drew you and you want another voice-driven thriller with a shocking twist

Final Verdict
Something in the Water earns its place in the Reese's Book Club lineup—not because it's literary fiction, but because it's a thriller that actually thrills. Catherine Steadman brings an actress's instinct for timing to her debut, building tension through a claustrophobic setting and a narrator whose reliability erodes chapter by chapter. The twist is worth the investment. If you're after a single-session thriller with atmosphere to spare, this one delivers. Check current pricing on Amazon using the link below.
