The Seven Songs of Merlin: The Lost Years of Merlin, Book Two

Young Merlin has brought new hope to Fincayra, the enchanted isle that lies between earth and sky. Having finally freed it from the terrible Blight, Merlin and the forest girl Rhia set out to heal the land using the magical Flowering Harp. But Fincayra remains in great danger still, and the first victim of the renewed tide of evil is Merlin's own mother.

Merlin's sole hope of saving his mother's life is to master the Seven Songs of Wisdom passed down from the greatest wizard Fincayra has ever known, Merlin's grandfather, Tuatha. Only then can he voyage to the Otherworld of the spirits and obtain the precious Elixir of Dagda. Yet to do that, he must first succeed where even Tuatha failed, by defeating Balor, the ogre whose merest glance means death. Even more difficult, Merlin must discover the secret of seeing not with his eyes, but with his heart.
