About this book:

Nora Hale, a disillusioned journalist turned podcaster, returns to her coastal hometown of Cedar Harbor after a teenager, Eli Mercer, discovers a human bone in the West Marsh. Her investigation into the remains reignites interest in three local cold cases: Hannah Reed (2002), Patrick Donnelly (2004), and Sloane Kerrigan (2010). Nora quickly realizes that the town’s powerful elite, led by developer Garrett Larkin and his enforcer Arthur Vance, have spent decades enforcing a code of silence to protect a lucrative but corrupt real estate empire built on stolen land and systematic violence.

Assisted by a cynical ex-cop, Jonah Pike, and armed with a brass anchor key from a mysterious local named Mae Thompson, Nora uncovers a trail of evidence including a hidden "killing room" in an old boathouse and a "ledger" documenting payoffs and land grabs. She discovers that her own late father was a reluctant accomplice to the Larkin family, having used his boat to move illicit cargo and later attempting to leave a trail of evidence for Nora to find. The mystery becomes deeply personal when DNA results link the marsh remains to Nora’s own maternal bloodline, revealing that the Larkins targeted specific families who resisted their influence.

The tension peaks as Nora releases her findings via her podcast, triggering a violent backlash from a community fearful of the truth. After surviving a harrowing abduction by Arthur Vance and discovering a second body on the Larkin estate, Nora and Jonah manage to secure the original ledger and a decades-old confession tape. These documents prove that the Larkins murdered the missing victims to clear the way for coastal development, even entombing one victim within the concrete of the town’s new pier.

In a final confrontation at the docks, the local and state authorities finally intervene, leading to the arrest of Garrett Larkin and the exposure of the town's structural corruption. While Vance remains a fugitive, the "tides of truth" ultimately prevail. Nora finds a sense of closure for the victims and her family, leaving Cedar Harbor transformed from a place of quiet menaces into a community forced to reckon with its dark history and the high cost of its long-held secrets.
