Jewel Of Atlantis

Legend claims the Jewel of Dunamis can overcome any enemy. Grayson James has orders to keep it from the wrong hands or destroy it. He doesn't know that the Jewel is actually a woman, not a stone! But once he meets this precious gem, destroying her is the last thing on his mind...
Jewel, part goddess, part prophet, is a pawn in Atlantis's constant power struggles. She needs Gray's help to win freedom and uncover the secrets of her mysterious origins. Gray needs her wisdom to navigate monster–ridden Atlantis.

But need blossoms into passionate love as they fight demons, dragons, vampires and a prophecy that says the bond between them could destroy them both.
