The fugitive is rescued by a kindhearted adventurer who gives it a name, the gift of communicating by handspeak, and an amazing truth it had never guessed. Now the girl Imrhien begins a journey to distant Caermelor, to seek a wise woman whose skills may change her life.

Along the way, Imrhien must survive a wilderness of endless danger. For the hearthside tales are all true. The unhuman wights are real in all their legions. They haunt every pool, every turn in the road, and threaten and torment all travelers. Lost and pursued by these monsters, Imrhien is saved by Thorn, a mysterious Dainnan ranger whose gallantry and courage are matched only by his martial skills. He becomes the girl's constant protector, steadfast and unstoppable. But, unknown to them, a deadly plot is unfolding, as a dark force summons the malignant hordes of Unseelie, and foul things amass in the night.

And as the journey grows longer, as the challenges grow more deadly, Imrhien discovers something more terrifying than all the evil eldritch wights combined: The girl with an angel's soul and a gargoyle's face is falling in love with Thorn.
