These books are such a treat. This is the fourth in the series and just when you think the world could not possibly get wackier, they introduce things like the Superhoop, a championship croquet game where each team has lawyers who file complaints (during the game) to try to disqualify the other teams chances. Or fictional characters who try to take over the world. There wasn't as much book jumping in the one, and it was kind of a nice change to get back to the "real" world, even though things aren't much saner there. I'm looking forward to continuing on with the next one.
