Space Winners [EPUB ebook] 

They were humanity’s hope — the first young people selected to leave Earth for study in the Galactic Federation. But something went wrong in deep space. Terribly wrong. Suddenly Jim Rawlins, Ellen Bouvier, Curt Harrington, and the squirrel-like Alien philosopher Peep were castaways, stranded on the quarantined planet of Quebahr — with no training, and little hope of rescue. Between them and the Federation’s emergency beacon were primitive Mauregs, aggressive Walats, lizard-like Noifs — plus danger, conspiracy and the mystery of an impending high-tech war on a backward peaceful planet. Without warning, the future of the two worlds — Earth and Quebahr — depended on three young humans’ ability to adapt and survive.
