Meet Lucas Densen, a 16-year-old high schooler who suddenly finds himself protecting Earth in a strange new realm--the world is literally in his hands!

Lucas Densen has earned his easygoing reputation through hard work and optimism. When not playing basketball for his high school team, the Pulsars, Lucas enjoys visiting his mother's archaeological excavations. During one visit, Lucas accidentally triggers an ancient alien artifact that suddenly transforms Earth into a small glowing orb no larger than a basketball! Transported to a mysterious realm with nothing but what's on his back and the planet in his hands, Lucas encounters a friendly alien, Lully, who offers to help. What awaits him in this new realm where worlds are the size of your palm, and can he find out how to restore Earth?
