This is book number 1 in the Tales from Alcatraz series.
When Moose meets Piper, the cute daughter of the Warden, he knows right off she's trouble. But she's also strangely irresistible. All Moose wants to do is protect Natalie, live up to his parents' expectations, and stay out of trouble. But on Alcatraz, trouble is never very far away.
Set in 1935, when guards actually lived on Alcatraz Island with their families. Choldenko's second novel brings humor to the complexities of family dynamics and illuminates the real struggle of a kid trying to free himself from the "good boy" stance he's taken his whole life.
