The first book in a fun, action-packed middle-grade series for heroes in training by Petra James and A. Yi.

Twelve-year-old Henrie is the first girl heir of the Melchior family in 200 years. This was deemed a dereliction of duty by the formidable Octavia Melchior, head of the House of Melchior (HoMe). For HoMe is in the business of heroes for hire.

Boy heroes, that is. Girls have no place. When Henrie receives a mysterious note, it sets off a chain of events including a kidnapping, a fancy skateboard manoeuvre and a private jet and she discovers 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.
