Kit McMahon lives in the small Irish town of Lough Glass, where everyone knows everyone; children who walk to school together grow up and become sweethearts and marry, people gossip and grumble and dream their lives away. For it is a place where change comes slowly. Until one day, beautiful, mysterious Helen McMahon disappears, presumed drowned in the lake, and then the gossip runs wild. The consequences for Helen`s husband, her son, but above all for her daughter, Kit, are unimaginable and will leave not one of their lives unchanged.
