Though Imrhien's memory is clouded by sorcery, she must take vital news to the King-Emperor of Caermelor. She hopes that there she may also find Thorn, the fearless ranger who has won her heart.Since no commoner may approach the royal court, Imrhien assumes a new identity as Rohain, a noble visitor from the distant Sorrow Isles. She soon discovers that the King and his rangers have departed to battle the unseelie hordes which have suddenly declared war against mortals.

Attacks by nightmare monsters of the Wild Hunt, led by the unseelie Lord Huon, grow ever more frequent and brutal. And when evil forces lay siege to the royal sanctuary on a hidden mystic island, Rohain is confronted with a horrifying discovery.

To protect those she loves, the Lady of the Sorrows must undertake a desperate quest to discover who she is and why an unhuman evil would wreak such destruction. But the truth of Rohain's past will prove more incredible-and far more tragic-than any she could possibly have imagined.
