By day, Wonderland is a magical amusement park boasting a certain retro charm. Excited children, hands sticky with cotton candy, run frenetically from ride to ride while the tinkling music of the oldest Ferris wheel in the Pacific Northwest fills the air. But behind the scenes, the rides need repairs, and the clown museum is filled with a lot more than just wax figures. Someone is working hard to keep the park’s dark secrets hidden beneath its weathered attractions.

Clues lead Vanessa into a mysterious web of missing persons cases that goes back decades. She moved to Seaside to escape her own scandalous past, but has she brought her family to the center of an insidious killer’s twisted game?
