On the island of By-the-Sea you could always smell two things: salt, and magic. Georgina Fernweh waits with growing impatience for a tingle of magic in her fingers—a magic that has been passed down through every woman in her family. Her sister Mary already has a gift for defying gravity, but Georgina fears her own gift will never come. When tragedy strikes, what made the Fernweh women special suddenly casts them in suspicion. Over the course of her last summer on the island—a summer of storms, of love, of salt—Georgina will learn the truth about magic, in all its many forms.
