Overall, this book can be summed up with one word: stupid.
But this is Christopher Moore, so I knew going into it that it would be stupid. This man is a genius of stupidity, if that makes any sense. He takes some really odd characters and basically makes their lives even more insane than they already were. I was pleased to see some of the characters from two of his previous books I've read, The Lust Lizard of Melancholy Cove & Lamb, were included in this book.
The setting is in Pine Cove, California, one of those trendy, artsy towns that you end up visiting and thinking it would be neat to live there. And then you leave. Basically there is a murder, a confused angel, and zombies. Yeah, it's pretty stupid.
My only beef with the book is when the R-word comes up in reference to the angel. In many ways I think Christopher Moore did a fairly decent job dealing with the word, but I just hate hearing or reading it at all. I know it's out there, I know it's used by a lot of people, but I hate it and I don't see the need for it.
Other than that, I overall recommend this book if you want to read something really stupid and silly. If you want to read something that's silly but profound, I recommend Lamb.
