The Four Lands, normally a land of magic and peace, faces a threat beyond man: Demons. Banished ages ago, they were held back by a magical wall known as the Forbidding. Yet the source of that magic, the magical tree known as the Ellcrys, is dying, and thus the wall wanes. When the acolytes who tend to the tree are all killed, the wise Druid Allanon turns to Amberle, the last remaining disciple, to save the tree. Only she can take the seed of the Elven tree to the faraway Bloodfire, to replant the Ellcrys and stop the Demons. To protect her, Allanon sends the young Wil Ohmsford, a descendant of heroes past. As the two youths head on a perilous journey, Allanon and the entire Elven Nation stand together to hold back the Demons and stop them from destroying the Four Lands.
