Ingledove and Lang's mother is dead, and their childhood home in Appalachia has been drowned under a dammed lake. When the two siblings journey by boat to visit her grave, they find an inscription added to her headstone: A daughter of Adantis. Lured by a glorious music that pervades the air, Lang wants to go deeper into the mountains. He and Ingledove cross the border into the hidden kingdom of Adantis, where the ways of the Cherokee and the settlers from the Old World have fused to make a wild new world. There, the bewitching fairy beauty and ancient evil of the singer nearly destroys Lang. To save him, Ingledove must find the man known to Adantans as the Master of Witchmasters, and draw on strength she isn't sure she has. . . .
