The Eternal Flame
T. A. Barron
 Avalon is at the edge of destruction. It seems as if the wicked spirit warlord Rhita Gawr has already gained his victory. The ancient tree has but tiniest hope in the young wizard Tamwyn, the apprentice priestess Elli, the fierce eagleman Scree, the graceful elf maiden Brionna, and the allies of Avalon who hope to prevail over Rhita Gawr's forces. The fate of Avalon lies in three key battles: one involves defeating an immortal serpent (Rhita Gawr himself) and relighting stars; one destroying a powerful crystal, the crystal of vengeláno created by Rhita Gawr; and one on the Plains of Isenwy that will result in the death of many innocent lives.
