This is a very helpfull tome that contains so much more then the usual "giggle-giggle-let's-talk-about-s-e-x" stuff that some other books provide. Great info on things like mating habits of non-human races, tabboos, marital customs, enough to make any race not just be humans with a differnt height, skin tone or pointy ears. Highly recomended.
Oh, and the art isn't bad either.
