The place is twelfth-century Wales, a land of forbidding castles and ferocious knights, sacred prophecies and unholy betrayals. In the bowels of the earth, deep in the caverns below the towers of Carn Merioneth, dragon nests await the arrival of one who holds the key to an ancient legacy. She is Ceridwen, daughter of a Druid priestess, unaware of her immense power - until fate leads her from the safety of a secluded abbey into the unbreachable tower of a feared sorcerer. Dain Lavrans knows he has no magic in himself, only the secrets of medicine he uncovered while a soldier in the Crusades. But with the appearance of Ceridwen, he will finally behold true - and terrifying - magic. For there are many who seek the maiden, none for her own good and all meaning to use her. Caradoc, the dreaded warlord whose father slaughtered her people and left her orphaned, wants her as his bride so he can claim the riches rumored to lie beneath Carn Merioneth. Helebore, a depraved ex-monk once sentenced to death for his sins, wants her blood so he can unlock the dark mystery of time. Rhuddlan, leader of the wild folk of the woods, wants her to take her rightful place as decreed by ancient prophecy. Dain simply wants the ethereal Ceri, for himself alone. Now a battle of epic proportion is about to take place. And at the center of the clash of power stand Ceridwen and Dain, struggling to escape the dangers and snares set by friend and foe alike, while discovering that neither can resist the love that promises to bind them forever.
