The Crusie/Mayer collaboration Agnes and the Hitman is one of my all-time favorite books (which is saying something, since I've read a *lot* of books). But I was disappointed with their Don't Look Down. I was really hoping for another Agnes with this book.
I'd put Wild Ride somewhere in the middle. But I'd definitely put it a lot closer to Agnes in the Crusie/Mayer spectrum. This story follows a group of people who work at a theme park in Ohio, which also happens to be a prison for five demons, the Untouchables. The premise was definitely outlandish, and surprising, considering the more real-life, action adventure tales of the first two books (i.e. no magic, no demons). But the kooky strangeness really worked here.
I'll never look at a theme park the same way again. A wild ride indeed.
