Bloodline. Wings In the Night, #13

Wings in the NightYour next vampire romance obsession She awakens cold and naked in the pouring rain, with no idea who she is or how she got there. But she does know one thing-she has to run for her life. When Ethan finds the terrified woman hiding in his stable, he knows exactly who Lilith is. He's never forgotten her, not in the three years since he escaped the facility where they were both captives, along with dozens of others, humans bred into vampires and brainwashed to be killing machines.
They'd shared one, innocent kiss. And then he'd escaped and left her behind. How can he tell her that he'd have taken her if he could, or that he planned to go back for her one day, once he found his brother and enough resources and help? He can't, especially not once her memory begins to return. But a new goal is even more vital then. How can he convince her that going back for the other captives would be suicide?
