Anna Emerson is a thirty-year-old English teacher desperately in need of adventure. Worn down by the cold Chicago winters and a relationship that’s going nowhere, she jumps at the chance to spend the summer on a tropical island tutoring sixteen-year-old T.J.
T.J. Callahan has no desire to go anywhere. His cancer is in remission and he wants to get back to his normal life. But his parents are insisting he spend the summer in the Maldives catching up on all the school he missed last year.
Anna and T.J. board a private plane headed to the Callahan’s summer home, and as they fly over the Maldives’ twelve hundred islands, the unthinkable happens. Their plane crashes in shark-infested waters. They make it to shore, but soon discover that they’re stranded on an uninhabited island.
At first, their only thought is survival. But as the days turn to weeks, and then months, the castaways encounter plenty of other obstacles, including violent tropical storms, the many dangers lurking in the sea, and the possibility that T.J.’s cancer could return. As T.J. celebrates yet another birthday on the island, Anna begins to wonder if the biggest challenge of all might be living with a boy who is gradually becoming a man.
