I am looking for a book on Greek Mythology that talks about all the Gods and Goddesses including the ones you don't usually hear about. I like the idea of Robert Graves's book called The Greek Myths, because it has so much information (about 1000 pages worth) on the Gods and goddesses, but I am looking for a book that is less of reference like Graves's. Thank you in advance!
I would love to find a book with all the originals.

Ok. so my assignment is to make up my own myth using gods and goddesses basing the story on the origin of something. I kinda want to do it on the origin of pain and suffering or something like that. But it would be REALLY helpful if you gave me some ideas. =) Please!~
THANKS!!!!!!!!~
