Twelve-year-old Henrie is the first girl heir of the Melchior family in 200 years. For the House of Melchior (HoMe), in the business of heroes for hire - boy heroes, that is - this is terrible news ... When Henrie receives a mysterious note, it sets off a chain of events including a kidnapping, a fancy skateboard maneuver, a private jet--and the discovery of something rotten at the heart of HoMe. As past, present and future collide, HoMe is poised to come tumbling down ... unless a new kind of hero can emerge from the rubble.
