Fleeing a hellish marriage, Ariadne Millar stumbles from her wrecked car into the storm-torn woods-and finds herself stranded in a strange land, its language alien, its eerie beauty surpassed only by its sudden, breathtaking violence.

A dark castle looms in the distance. A chained man begs for aid. Underdark has been waiting for a queen's return, and the only thing more frightening than the hallucinatory vividness of Ari's surroundings is the persistent sense that she has been here before.

Nightmare, hell, or bizarre reality? Each choice is more dangerous than the last, and time is running out as the Conjunction nears. Ari must thread her way through the maze, no matter the cost or consequences, for she has dreamed of a knight trapped in iron...

...and he, of course, has plans of his own.
