Not many kids have an island in their backyard, but suddenly, the Snolly sisters have three. They're staying at Granddaddy's seaside property for the summer, which includes the mysterious Fairy Islands: Fairy, Little Fairy, and Ghost. The people in Misty Cove call them "in-between places," and say they're full of magic - a magic that gets inside you. But ten-year-old Bee Snolly doesn't believe in magic - she just wants to help her ill Granddaddy. And if she and her sisters can unravel the mystery of the Fairy Islands in time, they may discover a long-buried secret that could help them all.
