This was a solid read, but I had trouble for the first 35% or so figuring out what the plot of the book would be and almost put it down. In the end, I stayed because of the humor.
Saul, a demon, and Tom, his human mark, meet when Saul decides to convince Tom to sell his soul in exchange for a night with Saul. Saul's POV is funny - he's a selfish, arrogant, demon, after all. Tom's is less so. He's a lonely comics artist and doesn't seem to have any reason to say no when Saul proposes the bargain. I was annoyed that Tom didn't care enough about his life to say no, but I also acknowledge that the book wouldn't have proceeded if Tom had walked away.
So Tom says yes and they have a lot of sex. The book has a lot of sex, in fact. The two of them are supposedly madly in love, but I really just saw them banging a lot. (This part of my review will probably sell a bunch of you on the book.) So now they've had The Sex and Saul starts having those dreaded Feelings for Tom. He burns the contract, since it hasn't been filed yet.
The rest of the book consists of them living on the run, getting caught, figuring out a way to be together. It's at around that 35% mark that we meet two new narrators, an angel and another demon, who've been sent to capture Tom and protect Tom's soul, respectively. I very much enjoyed reading their POVs, as I found our MCs to be a bit repetitive after a while.
If you like angel/demon stories, the show Supernatural, or ever wished your PNR with biblical references was gay, here ya go. I, for one, really liked that it was just obvious that God was on board with the relationship because they were so madly in love. Not even addressed, just natural and taken as a given by everyone in the book. ( )
