Crow has lived her entire life on a tiny piece of the starkly beautiful Elizabeth Islands off the coast of Massachusetts. Her only companions are Osh, the man who rescued her from a tiny skiff as an infant and raised her, and Miss Maggie, their neighbor across the sandbar. But it isn't until the night when a mysterious fire appears across the water that an unspoken question of her own history forms in her heart and an unstoppable chain of events is triggered. Using her bravery and perseverance, Crow must follow clues that not only lead to a personal treasure, but to uncovering her lost identity and, ultimately, understanding what it means to be a family.
