As the war between the mighty felinoid warriors from the planet Kzin and the wimpy leaf-eating monkey-boys from Earth rages on, one Kzin commander thinks he has the answer: learn from the monkeys and cooperate to destroy. But the humans know how to get the rivals of an enemy to cooperate, too. In another corner of the galaxy, Carroll Locklear is stranded on a planet with a group of prehistoric Kzinti. To survive, he must find common cause, if not with the males then with the females of that antique species. . . .
