From Back Cover:
Twelve-year-old Shelby Shodworth spends much of her life trying hard to add to her list of "thankful things." After all, the mysterious disappearance of her father when she was very young and the recent death of her mother have left her orphaned and living with a cranky uncle. But things are about to change for this ordinary girl who soon finds herself in a most extraordinary situation.
As a new student at Ms. Peabonnet's Academy for Girls, Shelby gets caught up in a mystery that involves a dark-cloaked stranger and a missing academy professor. Shelby, who has stumbled upon the professor's journal, makes a dramatic discovery: There is a time machine in the tunnels beneath the school.
