Torn by tragedy from his early life on a remote farm in Tasmania, Alex Dove has returned years later to start over. A chance encounter with quiet, alluring Merridy Bowman—a young woman similarly haunted by a tangled and catastrophic history—results in marriage, as two damaged souls unite to build a home, family, and livelihood far removed from civilization's bustle. Soon they are drawn into the unpredictable dynamics of small-town island life—and into the destructive orbit of an unscrupulous real estate agent who maintains a secret hold over both Doves. But when a shipwreck off the shore thrusts a troubled, possibly criminal teenage castaway into their world, Alex and Merridy's tenuously forged happiness is suddenly at grave risk, as they are forced to confront deeper questions about the true meaning of fulfillment.
