Breakneck Island: nestled precariously off the coast of Maple Bay, the lighthouse atop this rocky outcrop is all that stands between safe passage and nautical disaster.

For generations, the MacLeary family lived on Breakneck Island in an isolated and physically-demanding existence. One night in 1932, after a ruthless storm battered all of Maple Bay, the MacLearys disappeared without a trace, leaving behind only whispers of a missing fortune.

Nearly a century later, three people are drawn to Breakneck Island and its perplexing past: Peter Barnett, a recent Maple Bay transplant who’s piecing his life back together and possibly catching feelings for a charming professor; Dandy Feltzen, a wistful teenage girl searching for new beginnings while juggling the arrival of an unexpected visitor; and Cass Jones, a successful author given a cryptic tip for a haunting new story.

As Peter, Dandy, and Cass are drawn into the orbit of one of Maple Bay’s darkest mysteries, dangers past and present collide on the rocky shores of Breakneck Island, and the real story of the MacLearys finally comes into focus. But if the island is to reveal its oldest secrets, it may demand fresh bodies in return.
