Al Capone does my shirts - Gennifer Choldenko

When Moose Flanagan and his family move home, yet again, and become residents of the famous prison island Alcatraz, things get interesting. First of all, they share the island with a few other families and a lot of pretty heavy-duty criminals including Al Capone. And secondly, Moose's sister is starting a new school, which everyone hopes will help her become more integrated with those around her. When Moose comes up with some pretty cunning money-making schemes based on his famous co-residents, he does not count on his sister becoming inadvertently involved. This is a charming, funny and utterly enchanting book that skillfully and delicately weaves a humorous tale with some important issues.
