The Stainless Steel Rat's Revenge: Harry Harrison

Stainless Steel Rat Book V. It was totally impossible for Cliaand to wage interstellar war - but the crazy little planet was winning, whatever the odds. And there wasn't much the peaceful galaxy could do...except send Slippery Jim diGriz a.k.a. The Stainless Steel Rat to wage his own kind of guerilla campaign against the grey men of Cliaand and the leader, the indomitable Kraj. But then the Rat was aided by a band of liberated Amazons and his own beloved murderous Angelina - and they had to swing the odds in his favour! Cover art by Bruce Pennington.
