As a Category 3 hurricane bears down on New England, a luxury yacht grounds a deserted barrier island off the western end of Nantucket. When the Coast Guard responds, they find two people shot in the boat's cabin, one of whom dies soon after. Nantucket Police Detective Meredith Folger is called in to investigate - three days before her long-anticipated wedding. As the hurricane batters her beloved island and house full of wedding guests, Merry struggles to unravel a tangle of false identities, missing guns, and a cargo of heroin that's left one man in a coma. But is he a victim, or a killer?
