But before she can, they're stolen right from under her nose. Olive can't understand why anybody would want to steal the memories. As far as she'd known, her grandmother had always lived an utterly ordinary life.
Following the trail of the thief, Olive begins to discover that her grandmother's life wasn't what she thought. As she unravels the secrets lurking in her grandmother's past, she discovers clues Grandma Sylvie left her. It's up to Olive to solve the mystery of the memory thief, and in the process, learn about the incredible life and adventures of the grandmother she has never really known.
