On leave from the Minneapolis Police Department after being shot, homicide detective Brie Beaumont has gone to Maine where she has family roots. She ships out on the Maine Wind for an early season cruise with Captain John DuLac and eight others. Caught in a gale, they anchor off remote and windswept Granite Island. When someone aboard is murdered, Brie must single-handedly stage an investigation that moves from the ship to a small fishing village on the island. Plagued by flashbacks and fighting a growing attraction to Captain DuLac, Brie works to unravel a mystery that will place her directly in the path of a psychopathic killer.
