Damon nearly drowns. In the seconds before he’s pulled back, he sees a flash of a boy he doesn’t recognize, a child’s face in the dark water. He survives. But the image won’t leave him, and worse, the idea that dying again might be the only way to get it back starts to feel less like a thought and more like a plan. Someone helped him out of the water that day, and they’ve been watching him ever since. This book is connected to Marrs’ The Good Samaritan. It stands alone, but knowing that companion novel makes this considerably darker.

“Everyone on board had a reason to be here. Not everyone had a reason to be trusted.”

What It Actually Felt Like

John Marrs is good at writing characters who are not okay in very specific, believable ways. Damon’s obsession with his own near-death experience isn’t played as grief or trauma exactly, it’s something stranger and harder to name. He doesn’t want to die because he’s hopeless. He wants to die because something happened in that water that he can’t access with regular memory, and the not-knowing is eating him alive. That particular kind of fixation is uncomfortable to read because it makes a horrible kind of sense.

The “Good Samaritan” dynamic running underneath this story is what makes it more than just a psychological unraveling. The person who pulled Damon out of the water is presented as helpful, present, perhaps a little too invested in how Damon is recovering. That’s the shape of the threat here. Not violence that announces itself, but care that arrives too specifically, too attentively, from someone with their own reasons for wanting to be there. Marrs understands that a certain kind of predatory behavior wears a very warm face, and he builds tension from that without tipping into caricature.

The pacing is efficient in the way Marrs tends to be. He doesn’t linger when he doesn’t have to, and the short chapters push you forward even when you’re slightly dreading what’s coming. The crossover with The Good Samaritan deepens the context of who the helper is and what they’re actually doing there, and if you’ve read that book first, there’s a layer of dramatic irony that is genuinely unsettling.

The Honest Part

The obsession with dying to remember mechanism requires some convincing. It’s not a realistic psychology exactly, it’s a thriller premise, and how much it works for you probably depends on how willing you are to let Marrs set his rules and play inside them. I was willing. But I can see readers who need their character logic to be more grounded finding Damon frustrating.

Who This Is For

Readers who like psychological thrillers that work from the inside out, where the most dangerous thing in the story is what a character will do to themselves. I keep hearing if you’ve already read The Good Samaritan, than you should read this one, I haven’t yet but I do know this works on its own but knowing Marrs’ earlier work makes the threat hit harder.

⭐⭐⭐⭐  Marrs delivers again. I should stop being surprised.
