Most of us can remember a defining moment in our lives. A split second when time stood still and our lives changed forever. For Lily Ormond, that moment came late one night when she answered a knock on the door and discovered that while she'd been smashing garlic and rosemary and watching the soaps, her sister Alison had drowned.

Coming to terms with losing her only sibling and best friend was devastating, becoming a mother overnight to Ali's three-year-old son Charlie was mind-boggling, but discovering that her identical twin had been leading a secret life for years was almost Lily's undoing...

And so begins a journey linked with four men who'd been part of a life she hadn't even known existed. A journey that forces Lily to come to terms with a father who'd never really cared for her, a child who needs her too much and a sister who wasn't what she seemed.
