Fight like a man, or die like a slave.

Two years ago, Brooklyn Marshall was a happily married London policeman and amateur boxer with a promising future. Then he accidentally killed a rioter whose powerful father had him convicted of murder. To ease the burden on the prison system, the state sold Brooklyn into slavery. Now he’s the “Mean Machine,” competing on the slave prizefighting circuit for the entertainment of freemen, and being rented out for sexual service to his wealthier fans.

When barrister Nathaniel Bishop purchases Brooklyn’s services for a night, Brooklyn braces himself for yet another round of humiliation and pain. But the pair form an unexpected bond that grows into something more. Brooklyn hesitates to call it love—such feelings can’t truly exist between freemen and slaves—but when Nathaniel reveals that he wants to get Brooklyn’s conviction overturned, Brooklyn dares to hope.

Until an accident in the ring sends Brooklyn on the run, jeopardizing everything he’s worked so hard for. With the law on his tail and Nathaniel in his corner, he must prepare for the most important fight of his life: the fight for his freedom.
