Man-Kzin Wars XII

A man wakes up with over a month’s gap in his memory. He remembers being hired by a mysterious woman for a job with the condition that his memory would be scrubbed afterward. Obviously, the scrub worked, but now the police suspect him of murdering the missing woman. And a kzin is threatening him with much worse than anything the police would do.
The Protectors – powerful ancestors of the human race who live only to guard it and destroy all its enemies – have learned that the kzin have discovered a rich cache of anti-matter in deep space. One Protector brings a human out of stasis-sleep and enlists his involuntary help in her desperate mission to stop the kzin from gaining this source of unimaginable power.
