Basic Premise: Rules for playing werewolf (Garou) characters in the World of Darkness.
This book outlines the basics of the Garou nation- the tribes, auspices, enemies, allies, and everything else. It's pretty organized for a White Wolf book, and peppered with short stories for flavor. The art is good, if black and white, and expressive, giving fantastic context to the different elements being illustrated.
Werewolf was probably my favorite game to play and run from the entire White Wolf universe, as it had a good balance of combat, social interaction, magic, etc. It is a really well-written game.
