The Anniversary: A Thriller

Not yet published: Expected May 12, 2026

From the bestselling author of Parents Weekend comes one of the most anticipated thrillers of the year.

Today became an anniversary they would never celebrate.

One fateful night in 1992, Jules and Quinn’s lives 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 predator who strikes every May 1st in small Midwestern towns.

A year later, Jules is struggling with trauma and guilt, tormented by the question: Why was I spared? Quinn is newly released from juvenile detention and returns home to fresh heartbreak: 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 converge, 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 anniversary.

Twisty, high-concept, and emotionally charged, this novel 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. The Anniversary reaffirms Finlay as one of the leading thriller writers today.

This story follows Quinn Riley and Jules Delaney, two teenagers whose lives are forever altered by a violent night in 1992. Quinn, a boy from the wrong side of the tracks who was trying to do the right thing, and Jules, a survivor of the infamous May Day Killer, carry the weight of that night for years as the narrative revisits them every May 1st. The structure works well — short, digestible chapters and alternating perspectives between Quinn and Jules keep the pacing smooth and easy to follow. I especially enjoyed the literary references sprinkled throughout the novel; they add a thoughtful layer to an otherwise dark story. The characters are strong and well developed, even if a few plot threads feel slightly unresolved. That said, the book reads more like two parallel character studies than a tightly intertwined narrative. For much of the story, Quinn and Jules move through separate emotional journeys shaped by the same date but very different circumstances. Their paths intersect early on and again toward the end, but much of their development unfolds independently. While the premise promises a suspenseful serial killer hunt, the tension builds gradually and doesn’t fully grip until the final stretch. However, just when the story seems complete, the final twist delivers a satisfying surprise. Overall, this is less a high-octane thriller and more a reflective story about trauma, fate, and how brokenness can shape identity. A solid, character-driven read with emotional depth — especially rewarding for readers who appreciate introspective suspense.
