The wizards' battle against entropy and chaos continues in this, the ninth book of Diane Duane's "So You Want to Be a Wizard" series. Kit and Nita are part of the wizarding expedition that accidentally wakes up the long-sleeping Martians. Kit is entranced by them, but all is not well--they are a warlike people, and plan to colonize Earth!My summary makes it sound a lot more interesting than it actually is. There are far too many characters and not much plot. The vast majority of this novel is just wizards standing around deciding what to do, explaining what's happening, or rehashing what just happened. For a story about the revival of the Martians, this is surprisingly boring.
