Lucy Hull, a young children's librarian in Hannibal, Missouri, finds herself both a kidnapper and kidnapped when her favorite patron, ten-year-old Ian Drake, runs away from home. The precocious Ian is addicted to reading, but needs Lucy's help to smuggle books past his overbearing mother, who has enrolled Ian in weekly antigay classes with celebrity Pastor Bob. Lucy stumbles into a moral dilemma when she finds Ian camped out in the library after hours with a knapsack of provisions and an escape plan.
