So far as I can tell, the biggest problem with Christopher Moore is that his books are all checked out from the library and I have to wait a while to get another one. I read A Dirty Job a few months ago, then Practical Demonkeeping, and just finished Secondhand Souls. They're all hilarious. There's too much cussing (I think this about every book I read now which is a pretty good sign that I'm getting old and also want to be able to enjoy stories with my kids) and meandering plots, but they always make me laugh out loud. He also has clever eye-catching titles. I picked his books up originally because I saw the cover for The Stupidest Angel. It was all checked out on the library website, but I check out what was available and plan to work my way through pretty much all of his books now. Some of the characters' can be racially insensitive and others can be minstrelly at times, but it's never so bad I want to put the book down. It's also fun to see how the littlest set piece becomes important later on (Chekov's gun law is followed). I highly recommend reading everything he's putting down.
Nobody reads this stuff so I'm not going to fix the random thought order above. Instead I'm going to eat some blueberries.
