Hoka Series by Poul Anderson, Gordon R. Dickson

Meet the Hokas!...the most lovable - and the zaniest - characters you'll ever encounter in the entire Universe! Imagine how you would feel to be suddenly shipwrecked on a planet 500 light-years from the Solar System - and to walk into a 19th century, Old West frontier town! And then, to really shake your senses, you find the local citizens - in tremendous red bandanas, ten-gallon hats, chaps, high-heel boots and spurs - are pistol-toting teddy bears!

Following the advice of his father, young Charlie Stuart travels to a planet 200 light years from Earth and there finds himself involved in a political struggle.

One Hoka is a threat to human sanity. Two Hokas are a menace to civilization. And three Hokas . . . Heaven help the galaxy, in this hilarious science fiction adventure from two of the best writers in the genre.

If a human thinks he's Napoleon, it's time to get out a straitjacket. But when a Hoka thinks he's Napoleon, you'd better believe it! Just remember that with Hokas, reality is merely optional. . . .
