Amelia Albright dreams about going to Florida for spring break like everyone else in her class, but her father--a cranky and stubborn English professor--has decided Florida is too much adventure. Now Amelia is stuck at home with him and her babysitter, the beloved Mrs. O'Brien. The week ahead promises to be boring, until Amelia meets Casey at her neighborhood art studio. Amelia has never been friends with a boy before, and the experience is both fraught and thrilling. When Casey claims to see the spirit of Amelia's mother (who died ten years before), the pair embarks on an altogether different journey in their attempt to find her.
