One year ago, Leah's feisty twenty-one-year-old niece, Amy, mysteriously drowned near her family-owned luxury resort on the shores of Lake Garda. Now, Leah is returning to Italy for the first time since Amy's death. But what she finds upon her arrival shocks her: her sister, brother-in-law, and surviving niece, Olivia, seem to have erased all memories of Amy, and insist her death was an accidental drowning, despite murky circumstances. Leah knows she must look beyond the resort's beautiful façade if she is to uncover the truth of that night. Meanwhile, in Derby, university counsellor Joanna is recovering from a surprising break-up when she is swept off her feet by a handsome bartender. But when she invites him into her home, Joanna quickly starts to realise that she doesn't know him as well as she thought. What follows is a propulsive game of cat-and mouse as both women begin to realise that appearances can be deceptive: and that the darkest secrets often lie closest to home.
