This was an interesting sort of story. I knew when I accepted the book for review that it was the second in the series and was told that it could stand alone. I really felt that I was missing something by not reading book one in the series because I didn't really find out very much about Mercury or Christine and felt that there was a lot of backstory that would have made this a richer reading experience. The tone of the story is deeply ironic. I was told that it was funny but "funny" is so subjective. I didn't find it funny. To me it was more mildly amusing than laugh-out-loud funny. I especially enjoyed the footnotes which often went off on tangents and seldom illuminated the passage they were supposed to.The story essentially weaves the stories of Eddie Pratt - demon and would-be author, Jacob Slater - FBI explosions expert and a sufferer of something in the Asperger's spectrum, Mercury - low-level and seemingly amoral angel, and Christine - former reporter for a religious publication who tries to inject some of the human point of view to the situation. The basic plot seems to be thwarting whoever it is who is trying to destroy the Earth. The story jumps around in time from 2000 BC in Babylonia to the present day in Anaheim, California and somewhere in rural Kenya. The apparent villains are Tiamat - another low-level angel but with a strong desire to rule the world, Lucifer who apparently figured prominently in the first book, and crazed billionaire Horace Finch. I say apparently because it is not altogether clear to me who is was who was actually behind the plan to destroy the Earth or even if the plan really was to destroy the Earth. This story had layers on layers of conspiracy and each of the characters only sees a piece of the puzzle.The character I liked the most was Jacob Slater. I identified with his frustration at not being able to understand what caused the Anaheim Event and his phlegmatic acceptance of his kidnapping. His bit of the story did cause a few small chuckles.This is a story for those who like absurdity and some social commentary in their fiction. It is designed for those with a quirky sense of humor. I liked the style of the book and found the prose very readable.
