Prophecy says Ula, an Irish princess, is destined to rule the Enchanted Island with a black-eyed prince. For safety, she hides in the Pine Barrens of New Jersey with a druidess for a companion. Ula knows nothing of the modern world. She has no friends and never saw a man. When her druidess is kidnapped by the evil Balor, she leaves her hidden cottage to borrow a dog who can aid her in finding her companion.

Shay is a descendent of Irish kings given specific rules to follow since birth. If he breaks his sacred code misfortune or even death could result. He doesn't think those principles make sense in the modern world. Then he meets Ula. She walks into a pub during a blizzard and causes a melee. He wants nothing to do with her, especially when he realizes she's out to steal his dog but if he turns her out into the snow, he'll break his sacred code. Though Ula spouts nonsense, she tempts him to abandon every principle his father taught him.

Ula's love for Shay is forbidden, for he has blue eyes, but the powerful emotions that draw her to him cannot be denied. Still, she must rescue her druidess and for that she must take Shay's dog, even if Shay breaks her heart and winds up hating her forever.
