Not quite as trashy as it sounds, but devilishly humourous, and risque in all the right places!  I too was pleasantly suprised to find it gay and lesbian friendly and enjoyed the literary and mythical allusions.  Brilliant!

I've read alot of astrology books but this one is the absolute best so far. Not only is it well written, it also includes mythology that I have never seen in any other book which helps to understand the basic nature of the signs and how they apply to you.
I also dig the fact that it is gay and lesbian freindly as well as gender concious. More books like this one please!
