Allegra thought her wedding day would be one of the happiest days of her life. Instead, she ends up shipwrecked on an island with her fiancé and two friends. Cold and wet, she and her friends need to repair their boat and get back to Aurelia.

But it turns out being cold and wet is the least of their problems. Because they haven't landed on just any island. They're on Ghost Island, one of the Forbidden Islands. For seventy-five years, the Dark Fairies have been imprisoned on the islands. They're unbelievably powerful.

And they hate humans.
