Elyon is a fairly unknown character from the last DoSaB book. Issa is one of the most known characters there are. They have "moments" in the book, but it ends before we know what happens. So what does happen? What if they were brought together to root out a group of rebels set on killing all Angel and Chimaera who would dare being together? What if they became one of the targets?

Demons Angels. Same old same old. Angels fight against the demons, and neither side ever really wins. So they're fighting again (big surprise) and Hell is on the side of humanity this time, for once. So Angeline Darsam, Queen of whores, gets nominated to lead the not-quite human forces of Hell against the not-quite sane forces of Heaven for the first time. So, we're doomed, really.
