The family curse has been lifted, and the Widdershinns sisters--Betty, Fliss, and Charlie--are free to leave the misty prison isle of Crowstone. But when a mysterious girl arrives at their inn accompanied by a will-o'-the-wisp, or ghost, it

seems another adventure has landed on their doorstep. The stranger, named Willow, is an escaped prisoner, desperate to clear her father's name before he's executed for a crime he didn't commit.



Then Charlie is kidnapped by poachers, swept away on a dangerous mission in search of pirate treasure that's protected by a vengeful ghost. Betty, Fliss, andWillow pile into their trusty boat and embark on another incredible journey, one

that involves ghosts, fierce pirates, and an island that exists only in legends. Can Betty and Fliss save their sister--and themselves--once more?
