I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Well, the narrator's decent. But so far I feel like this is going to be a terrible book. I have a gut level dislike of Simon, the main character.
Simon accidentally opened his front door for the first time in over a decade, only to find a demon (her cleavage has been frequently mentioned) and an angel (male in appearance and therefore much less interesting to Simon). They both want something. I'm going to guess it's the carpet mentioned in the description.
I'm considering turning this in and checking out something else. Unfortunately, I've listened to almost everything my work library and public library have in their Overdrive audio collections that seems likely to interest me.
