**From a New York Times–bestselling author, plane crash survivors must cross a desert and face mechanical and supernatural threats in order to find rescue.

The survivors have made it out of the jungle, but they may be sorry they ever left when they stumble upon a whole new ecosystem, populated with entirely new threats. And the greatest threat of all may come from within. Because one of the kids is changing into someone they no longer recognize.

The seven-book series begun by #1 New York Times bestseller Scott Westerfeld only gets bigger and bolder under the frenzied imagination of New York Times–bestselling, critically acclaimed author Jennifer A. Nielsen!
