Recovering from a gas that caused him to sleep for five hundred years, Anthony "Buck" Rogers helped an enslaved America strike its first blow for freedom against the alien Han.

Bruce Gordon was an ex-fighter, ex-gambler, ex-cop, ex-reporter, and now he was an ex-patriot of Earth. Security shipped him to Mars with a knife, 100 credits, and a yellow card that meant no return. An SF novel that would appeal to Mickey Spillane fans, Police Your Planet features lots of hands-on violence, assorted beatings, and blood. But this isn't just a crime novel put into space; this is a hard sf novel, and the terraforming of Mars, while not dwelt upon, is central to the story.
