CHRISTINE BRODIEN-JONES studied writing at Emerson College in Boston, and has been a journalist, an editor, and a teacher. She now splits her time between Gloucester, Massachusetts, and Deer Isle, Maine. Look for her other book for young readers, The Owl Keeper, available from Delacorte Press.

Eleven-year-old Zoé Badger, imaginative, carefree and adventurous, lives a transient life, moving with her mother from one town to the next-except for summers, when she stays with her granddad in Tenby, Wales. But when she and her cousin Ian discover a glass puzzle that's been hidden away for decades, ancient forces are unleashed that threaten to change their safe-haven summer town in sinister ways.
