About This Book
The sharp crackle of the asteroid storm fills the air as Kitai's ship shudders violently, metal groaning under the cosmic assault. Stranded on a wild, strange Earth, Kitai feels the weight of the unknown beneath his feet and the fierce hope in his heart. With his father's life fading, every step into the wild is a step toward becoming the hero he's always dreamed of being.
