You should check out Elliott Kay's 'Good Intentions' series of novels. It's a fun series about a man who interrupts cultists performing a ritual that ends up with him bound to an angel and a succubus. It's the first thing I thought about when I saw this.
i know about it. someone mentioned it before and i gave the first book a start worried that it would be too similar. but no this is nothing like it.
in fact, there are no angels or demons in this story at all this goes somewhere entirely different.
