Twelve-year-old Caroline is a Hurricane Child, born on Water Island during a storm. Coming into this world during a hurricane is unlucky, and Caroline has had her share of bad luck already. She’s hated by everyone in her small school, she can see things that no one else can see, and — worst of all — her mother left home one day and never came back. With no friends and days filled with heartache, Caroline is determined to find her mother. When a new student, Kalinda, arrives, Caroline’s luck begins to turn around. Kalinda, a solemn girl from Barbados with a special smile for everyone, seems to see the things Caroline sees, too. Joined by their common gift, Kalinda agrees to help Caroline look for her mother, starting with a mysterious lady dressed in black. Soon, they discover the healing power of a close friendship between girls.
