Science fiction. The tezkos do not understand violence and have never had a war in their long history. When they are attacked by vicious aliens, they are forced to find experts in warfare and forge an uneasy alliance with them. When the Tezkos arrive on Earth, they are not interested in our science, our art, or our culture. They want us to fight an interstellar war for them. In return, they offer us something of which we can only the stars.
