I think I have an issue getting through the first chapter in any Moore book, save Lamb.  I read the first chapter and almost gave the book up as a lost cause, but a stressful day had me reaching into my bag for it and I'm glad I finished it.  I like how Moore weaves together multiple characters and events, including sometimes silly, pointless side lines of things that happen as a result of the plot.  His characters are always diverse, interesting things, and often times display attributes true to people I've known.  I think what I like most about Moores' books is the plot; it's always quirky, well thought out and diverse.  The climax is simple and not all that complex but it is engaging and you know exactly what each character could loose or gain by the resolve.  Now, with that said it's also good to note that Moore often writes from the perspective of a pervy, lewd man sinking into her geriatrics unwillingly, so this isn't for someone who is easily offended by the thoughts I know all honest people probably have.  I laughed, I awe'd and I enjoyed, Practical Demonkeeping - but it's not a book for everyone.
