The ocean has always flowed through Sophie's life. It promises journeys of adventure and discovery – she is drawn to it. And when she gets the chance to cross the Atlantic on board her uncle's boat, The Wanderer, she can't wait to set sail.

But troubled Sophie has a secret, and deep down she's terrified of where The Wanderer will take her. For this storm-tossed voyage will also be a journey into the mysterious past of her forgotten childhood. And she, and the rest of the crew aboard, may not survive it.
