The Angels seem slightly, just SLIGHTLY overpowered XD

I mean, some of them should have died in the attempt to kill Zeus. But thats my opinion

Very interesting first chapter. It really reminds me of a story in the same vein as Supernatural (the TV show)/Good Omens (the book), so if that's what you were aiming for, kudos. I hope you keep up with this, as you've set yourself up to write some potentially very entertaining stories, and your writing style lends itself well to easy reading. Your dialogue was superb, as well.

I'll keep reading.

This is really, really interesting :D

Keep on writting, it looks epic :D
