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.
