Cammie O'Reilly is the warden's daughter, living in an apartment above the entrance to the Hancock County Prison. But she's also living in a prison of grief and anger about her mother who died saving her from harm when she was just a baby. And prison has made her angry. No wonder her nickname is Cannonball. In the summer of 1959, as 12 turns to 13, everything is in flux. Cammie's best friend is discovering lipstick and American Bandstand. A child killer is caught and brought to her prison. And the only mother figures in her life include a flamboyant shoplifter named Boo Boo and a sullen reformed arsonist of a housekeeper. All will play a role in Cammie's coming-of-age. But one person in particular will make a staggering sacrifice to ensure Cammie breaks free from her past. Master storyteller Jerry Spinelli spins a tale of loss and redemption like no other. The Warden's Daughter shows kindness and compassion can often be found where we least expect it.
