When the peaceful world of Avalon (contained on the roots of a supernaturally big tree) begins to suffer mysterious droughts and darkness, the heir of Merlin is the only one who can save it. But is 17-year old Tamwyn the heir, or is he the child of the dark prophecy, who is destined to destroy Avalon? Loosely tied to the author’s Lost Years of Merlin series. Sequels: Shadows on the Stars, The Eternal Flame.
