HEART OF GLASS
by Jennifer Hillier
Minotaur/St. Martin’s Press, August 2026
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.

Jennifer Hillier was born and raised in Toronto, Canada, and lived in the Seattle area for years before returning home to Toronto, where she now lives with her family.

All it takes to unravel a life is one little secret… Marin had the perfect life. Married to her college sweetheart, she owns a chain of upscale hair salons, and Derek runs his own company. They’re admired in their community and are a loving family―until their world falls apart the day their son Sebastian is taken. A year later, Marin is a shadow of herself. The FBI search has gone cold. The publicity has faded. She and her husband rarely speak. She hires a P.I. to pick up where the police left off, but instead of finding Sebastian, she learns that Derek is having an affair with a younger woman. This discovery sparks Marin back to life. She’s lost her son; she’s not about to lose her husband, too. Kenzie is an enemy with a face, which means this is a problem Marin can fix. But as she sets a plan in motion, another revelation surfaces. Derek’s lover might know what happened to their son. And so might Derek.
