Nora Galloway left Cairn Harbor twelve years ago and swore she'd never return. But when a letter from her dead mother's attorney drags her back to the fog-drenched coast of Maine, she finds her childhood cottage locked — and the key in the hands of a brooding lighthouse keeper named Silas Wren, a man who knows far more about Margot Galloway's secrets than any stranger should.
Her mother's will hides a locked room. The locked room hides a twenty-year investigation into the town's poisoned water. And the man who poisoned it will do anything to keep the truth buried — including murder.
As Nora digs deeper into her mother's hidden case files, she uncovers a trail of environmental crime, family betrayal, and a death that was never an accident. Silas — scarred, solitary, bound by a promise to a dead woman — holds the final pieces. But trusting him means trusting the one person her mother chose over her.
