Here is the back jacket for The Digging Crew:
When the women of crew 56 planned their escape from the hellish prison-mine of Carmel 5, they thought of everything…well, almost everything.
Sammy’s life is a nightmare, and it’s all her fault. First, she is caught shoplifting—a big no-no in the hard-on-crime Dominion’s world—and is shipped to a prison-mine for women on a faraway desert planet. Then on her first week there, she destroys a droid belonging to the prison…on purpose. So when she’s sent deep into the pit of the mine as punishment, Sammy doubts she’ll live to see her sixteenth birthday. After all, this is the diggers’ level, and they are the prison’s most violent criminals. To her surprise, she finds a new family in one of the digging crews. But she also makes a deadly enemy. Can she and her crew manage to escape the prison and regain their freedom?
