What are some books about demigods?

Well...the Magic Bites series by Ilona Andrews has a character that's the son of a demigod (or something along those lines) that's kind of an important character. He isn't known as the son of a demigod until the third book, but it's all that I can think of at the moment, and the series is amazing. It's an adult book, but I'm a teenager, and I can tell you right now that they're nothing explicit in the story, really, and the things that may be mentioned aren't anything that you wouldn't hear one time or another in school. The series is amazing, though, and I'd really recommend it, even if it isn't really "about" demigods. But, like I said, it has a character that's like 1/4 god or something, and it's a really good series. In the second book, Magic Burns, I think that there are some characters that have to do with myths, not sure if they're demigods or gods, but it does have to do with myths and mythical creatures. The series is amazing, though, and it's all that I can think of at the moment. Good luck with finding something! =]
