The Vampire's Bride by Gena Showalter
Enter a world of dragons, demons and nymphs...enter a world of dark seduction and powerful magic...enter Atlantis...He is Layel, king of the vampires, a master seducer no woman can deny. But since a rogue horde of dragons killed his beloved over two centuries ago, Layel has existed only for vengeance...until he meets Delilah. Wary of love, the beautiful Amazon wants nothing to do with the tormented vampire. Yet there's no denying their consuming desire every time he nears her. Neither trusts the other - nor can they survive alone. For in an impossible game of the gods' devising, they've been trapped on an island, about to face the ultimate challenge: surrender to the passion that will bind them forever...or be doomed to an eternity apart.
