Comedy; Young Adult Literature
We found ourselves laughing out loud while reading this book. First of all, it's funny to hear someone so enthusiastic and confused by things we take for granted everyday. Take when Kiriel smiles:
Teeth. I was grinning! That was wonderful, too—facial muscles reflecting emotions, which are some of the most intangible things in existence. What an exquisite world this was! I should have come here sooner. (2.6)
We don't know if we've ever called the act of smiling exquisite. Yet, somehow our favorite Fallen angel makes it work. The book is about serious stuff—hell, sin, punishment—but it's told with a light twist to it. So while there's a dark element underneath it all, this book is ultimately about Kiriel's success, so comedy it is for this book genre-wise.
As for young adult, well, this book involves a demon stepping into the life of an average American teen. To this end, there's lots of interest in classic teen stuff: school, sex, siblings, and all that jazz. The language is easily-digestible for young adult readers, and all of this combined makes this book definitely fall into the young adult lit category.
