Twelve-year-old George has no idea what to expect when she's sent to stay with eccentric relatives following the disappearance of her brother. Soon after her arrival, she learns that Uncle Constantine has been kidnapped. George sets off to recover him and is joined by two orphaned boys along the way and Cavendish, a talking map. Together they visit magical worlds full of monsters, witches, and dragons as they attempt to find Constantine--the Timekeeper--a man of great significance. If he's not rescued, events will cease to happen at their designated times, disrupting the unfolding of the universe. Can this ragtag crew save the future before being outwitted by evil captors?
