An Ancient Cherokee prophecy, a dying planet, two alien races laying claim to Terra, our Earth, and four clueless teens expected to save it all ... What could possibly go wrong? Jewel Adam's special gifts forced her into a life of solitude as a young child, with only her parents as companions. Things change during her senior year in high school, when she discovers she's not the only one with enhanced abilities. Jewel, Sky Fletcher, her twin brother Pax, and Storm Ryder share more than the unusual shape and brilliant colors of their eyes. They have powers, and they share a destiny. Are their powers enough to save the planet? Terra's fate hangs in the balance. Will an ancient enmity between two star-systems cause them to fail? Are they willing to take the chance and risk their lives for mankind? If you like I Am Number Four or The 5th Wave, you'll enjoy P.T.L.
