Children of the Star: The Complete Trilogy
by Sylvia Engdahl
Omnibus edition (box set) of the trilogy This Star Shall Abide (aka Heritage of the Star), Beyond the Tomorrow Mountains, and The Doors of the Universe. Noren was a heretic—he defied his world’s High Law and had no faith in the Prophecy's fulfillment. But the more he learned of the grim truth about his people's situation, the less possible it seemed that their rightful heritage could be restored.
