In his quest to become the first human Galaxy Ranger, Zack Jackson braved the untamed wilderness of a half-terraformed world, was chased by hungry predators, and made friends with strange beings from alien civilizations. Zack thought going to the prestigious Cytherean Academy would be a piece of cake compared to all that. He was wrong. Even though his friends Ix and Jenny would be there, Zack worried about meeting the other students. Would Zack's new friends be from another part of Earth, one of the colonies of Alpha Centauri, or the other side of the galaxy? And what secrets could he discover in Cytherean Academy's seven domes?
