All I can remember about it was that it was a contemporary romance about a guy who finds out he is the son of some greek god, I think it was Posiden, when he is like kidnapped or something. He leaves behing a pregnant girl friend and does not return for like 7 years or something and tries to reconnect with them.
Sorry I could not think of anything else.
I would really like help in finding this book, I have looked forever. : (
