Wicked Crazy Vampire Love by Cassandra Lawson

Twenty-five years ago, an alliance was formed for the purpose of starting a war between vampires and hunters. When their plot was abandoned, all traces of their secret order were destroyed… or so they believed. A child who is both hunter and vampire survived. To keep her safe, her true nature has been hidden for more than two decades. Now, the original members of the order have joined forces once more for a single purpose—to kill the young woman before anyone can discover what she is.

Raised to be the perfect killer, Drew never expected to be anything more. Watching his cousins find true love, he longed for more, even knowing he was too broken. When his vampire family joins forces to stop a plot that could end the truce between vampires and hunters, Drew is thrown together with a woman who is not what she seems. She is far from Drew’s type, but he finds himself unable to stay away from her. As he tries to find a way to keep her safe, he begins to wonder if she may be able to love him for who he is—faults and all.
