Embraced by Blood by Laurie London
Two vampire coalitions are waging war...And Alfonso is a hunted man. He's managed to elude the Darkbloods, vengeful foes who won't rest until he's dead. But he still craves one dangerous temptation: Lily, the sexy Guardian agent he'll risk anything to protect. Lily is a wanted woman. Her talent for tracking Sweet - a rare blood type that's addictive to vampires - makes her a target for enemy capture. Her only hope is the vampire who stole into her bed...then left her in despair. Lily won't let Alfonso near her heart again - until an irresistible hunger threatens to draw them back together...and into an assassin's snare.
