I am happily paired, but purchased this book because i am a huge fan of block's. i always found it fun to read astrology books, but was never all that into it. this book really captures a lot that i felt was missing in astrology. the "types" are very very very well done, and as another reviewer said, you will start to "see" them all around you immediately! i think this may be because astrology forces you into one category whereas block takes into consideration the make-up of the whole individual, including physicality, drive, sexual appetite, passions, style, and everything else you may find important when you're trying to find your match! there is even a section for mixed types and pairings of the same sex! not only do i think this book will help my writing (it is so imaginative and i think that the "types" will help me to round out my characters,) but i think i discovered why i crave attention so much. my mother is clearly a banshee, and yes, her marriage to my "hob" father is definitely a strange match! block hits it on the nose every time. i completely recommend this book! another plus: the awesomely beautiful illustrations by fumi nakamura!
