Meg Drury, librarian and master of people repelling, finds herself lost for words when the mysterious 'Johnno' visits her natural habitat to return her misplaced library book. Once Meg recovers her powers of speech, and fails to deter Johnno despite her best attempts, an unlikely romance blooms. Oozing with confidence and bad boy charisma, Johnno has Meg wondering if he might be even better than the eighty percent perfect her well-meaning mother has encouraged her to settle for. But Johnno's mathematical advantage is seriously challenged when Meg discovers he has a list of secrets longer than her overdue loans history, and she must decide if not quite perfect is worth risking it all.
