Ever since her dad died, 11-year-old Jerry Blum and her mom have bounced around dead-end towns, staying in a series of rundown motels where her mother picks up housekeeping work and Jerry can get around in her wheelchair. But the Slumbering Giant motel is different. Lights blink on and off in the surrounding trees, a mysterious radio station plays only at midnight, and people disappear into the woods, never to been seen again. Not to mention that...

Teaming up with new friend Zita the spacegirl, Jack and Lilly confront an army of dangerous giants and screeds ready to lay siege to Earth and determined to end all human life.
