Thirteen year-old Gabriel Hunter, a Lesser, woke one morning to find he's been catapulted to Kata-Tartaroo, the scariest place imaginable, and hidden deep beneath the world of Lessers and Moors. No adults, no way to communicate with the Above World and a forest filled with a myriad of creatures including Demon Owls ready to eat you whole if you try to leave. No one has ever broken out of Kata-Tartaroo alive, but when Gabriel, Corinna Fornax, and Owen Agnitio, two Moors, solve a math problem stored in the program of an obsolete tablet, they get some unexpected help. They have 24 hours to collect three mystical objects and escape Kata-Tartaroo. Gabriel must decide to trust these two Moors through this perilous journey and that won't be an easy thing for him to do. Moors and Lessers are segregated in the Above World. They are raised to be enemies. Will he be able to put aside his beliefs long enough to get away? Or will he be lost in Kata-Tartaroo forever?
