Lucas by Cynthia Breeding

She’s a white witch. He’s a shape shifter. Who casts the first spell?

Once a knight, shape-shifter Lucas Ramsey has come to the 21st century to retrieve a hidden relic of the Templars. If the evil, one-eyed god Balor—exiled from Avalon—finds it first, the world could be annihilated. Fiesty, white witch Sara Kincaid has no plans to share the medieval manuscript her boss sent her to Sotheby’s auction to purchase. Not even with the tawny-haired, golden-eyed stranger who looks like Adonis…and who is probably crazier than a loon since he said the manuscript holds a clue to finding a magical spear. Like it exists.
