Read Edith Hamilton's Mythology. It's filled with wonderful and G-rated stories from the myths. I do like that it has a bunch of myths squeezed into the book (it's quite a big book, too), but sometimes it's sporadic and bounces everywhere. It's still a good source.

Also, I'm kind of a huge
Greek geek when it comes to Greek mythology, so you're welcome to mail me any time.
