"전 항상 꿈만 꾸는 소녀가 아니에요, 그저 바다가 저를 불러요" 우리 아빠는 저를 삼중인격자 Sophie라고 부른다. 한 면은 꿈꾸기 좋아하고 낭만적이라는 것이고, 또 다른 면은 이성적이고 철두철미한 면이고, 세 번째 면은 충동적이고 고집불통이라는 것이다.
13살짜리 Sophie는 양부모의 걱정을 뒤로한 채 그녀의 삼촌과 사촌과 함께 코네티컷에서 시작해 대서양을 지나 영국으로 가는 항해에 오르기로 결심한다.
이 모험천만한 대서양 횡단여행은 어린 독자들로 하여금 바닷바람과 짠내 나는 물살을 느끼게 해줄 것이다.

The sea, the sea, the sea. It rolled and rolled and called to me. Come in, it said, come in.
Thirteen-year-old Sophie is the only girl amongst the surely crew of The Wanderer, made up of her three uncles and two cousins. They sail across the Atlantic toward England, the land of Bompie, her grandfather. The sea calls to Sophie-promising adventure and the chance to explore and discover. But the personal journey she takes brings her deeper into a forgotten past than she ever knew she could travel to.
Sophie's thirteen-year-old cousin Cody isn't even sure why his father brought him along on this voyage. Everyone, including his dad, thinks he's nothing but a knuckleheaded doofus. But behind all the goofing off, he wonders if he has the strength to prove himself to the crew and to his father.
Through Sophie's and Dody's travel logs, the amazing experiences of these six wanderers and their perilous journey unfold. Stories of the past and the daily chalenges to survive at sea swirl together ans the Wanderer sails toward its destination, and its passengers search for their places in the world.
