Synopsis:
Every Year He Comes For Them.
On one fateful night in 1992, the lives of two seventeen-year-olds are changed and intertwined forever. Quinn Riley, a boy from the wrong side of the tracks, is arrested after he innocently tries to break up a fight but ends up nearly killing someone. Jules Delaney, high school royalty, survives an attack by the elusive and terrifying May Day Killer—a serial predator who strikes every May 1st in midwestern small towns.
A year later, Jules is struggling with trauma and guilt, tormented by one question: Why was I spared? Quinn is newly released from juvenile detention and returns home to fresh the unsolved murder of his mother.
Over the next decade, their lives are revisited on a single day each year—May 1st. As secrets unravel and the paths of Quinn and Jules collide, two mysteries edge closer to the truth. All the while, the May Day Killer is still out there—and the clock is racing toward another May 1st.
The Anniversary is an utterly compelling story of the hunt for a serial killer. But it’s also a heartfelt—and heartrending—novel about fate, innocence lost, and two souls who find that sometimes being broken is the only way for the light to get in.
Review:
The Anniversary by Alex Finlay is easily his strongest work to date, and that’s saying something if you’ve followed his thrillers. From the opening pages, the structure alone hooks you: we check in on Quinn Riley and Jules Delaney on the same day each year—May 1st—watching their lives fracture, shift, and slowly spiral toward something far more connected than they could ever imagine. It’s a simple concept on paper, but in execution it’s incredibly effective, giving the story this fractured, almost cinematic rhythm that makes it impossible to put down.
What really elevates this book is the pacing and structure combo. The chapters are razor short, constantly pulling you forward with just enough detail to make you say “one more chapter” until suddenly you’ve read half the book. Finlay balances the dual mysteries—the fallout of a near fatal teenage incident and the chilling presence of the May Day Killer—with precision. It’s twisty without feeling chaotic, emotional without losing its thriller edge, and smartly layered so every yearly snapshot adds weight to what came before.
There’s also something unexpectedly poignant about it. Watching these characters over a decade, always on the same date, creates this quiet sense of fate and inevitability that lingers beneath the suspense. Quinn and Jules are both shaped by trauma in very different ways, and the way their paths gradually tighten toward each other feels earned and gripping. Add in the serial killer thread that never quite lets you relax, and you’ve got a book that’s both bingeable and surprisingly emotional. This is a perfect summer thriller, it’s dark, addictive, and absolutely unputdownable, don’t miss it.
