The sea, the sea, the sea. It rolled and rolled and called to me. Come in, it said. Come in... The ocean has always flowed through Sophie's life. It promises journeys of adventure and discovery. 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 Sophie has a secret. 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 motley crew aboard The Wanderer, may not survive it.
