Once upon a time, in the very earliest days of interplanetary exploration, an unarmed human vessel was set upon by a warship from the planet Kzin -- home of the fiercest warriors in Known Space. This was a fatal mistake for the Kzinti, of course; they learned the hard way that the reason humanity had decided to study war no more was that humans were so very, very good at it.

And thus began THE MAN-KZIN WARS. Now, several centuries later, the Kzinti are about to get yet another lesson in why it pays to be polite to those hairless monkeys from planet Earth.
