Jennifer Hillier

Heart of Glass

Coming August 25, 2026

A serial killer recants his long-ago confession regarding a small-town high school girl—and her then-best friends are forced to confront what really happened that night and what’s happening now.

Twenty-five years ago in Seaside, Washington, a charming drifter named Sam met three inseparable teenage girls at the local amusement park. Days later, one of them was found dead, her body surfacing in a flooded cranberry bog not far from where she was murdered.

Barb and Nicolette were shocked to learn that the man they all met at Wonderland was the Carnival Killer. After he’s arrested for the murders of five young women—one of whom was their best friend, Lorelei—Nicolette moved to the city to pursue her dreams of being famous. Barb stayed behind in Seaside, eventually becoming a reporter for the local paper. Their past safely behind them, they’ve both moved on with their lives.

But when the Carnival Killer recants his confession and a new body washes ashore on the eve of Wonderland’s grand reopening, the secrets that Barb and Nicolette have worked so hard to bury begin to resurface, threatening to destroy everything in their carefully constructed lives.
