Showing Al Capone Does My Shirts by Gennifer Choldenko

Moose Flanagan lives with his family on Alcatraz Island - home to a high security prison and the famous gangster Al Capone. But living next door to Al Capone is the least of Moose's problems. He has a new school to get used to and new friends to make, and his mother is so busy looking after his sister that she has no time to listen to his concerns. When Moose and his new friends come up with plans to make money out of the convicts things start to look up. Until his sister Natalie poses an even bigger problem to him than she usually does.
