Chained by Night (Moonbound Clan Vampires, 2)

Leader of the vampire clan MoonBound, Hunter will do what he must to save his people from extinction-or worse, a torturous eternity as vampire slaves and subjects of human experimentation. To keep his enemies at bay, he has agreed to mate a rival clan leader's daughter in return for peace between the clans and an ally in the looming war with the humans.

But survival comes at a price. First, Hunter must break an ancient curse by successfully negotiating three deadly tests. Then he must resist the searing passions of the gorgeous vampire warrior he despises but is bound to mate with. Will Hunter stay true to his word? Or will he risk everything for the woman he really loves: the vampire seductress's identical twin sister?
