Tasi, an eighteen-year-old, head-strong, blood-drinking, dhampyr, has been hidden away in a small town in Maine since the death of her parents. Though she had trained to fight and kill vampires, she never believed those skills would be useful in her mundane life. That's where she's wrong.

In one moment, her life changes forever, and her aunt's final words ring in her head.

They want your blood.

Now orphaned and charged with protecting her sister, Emily—a sister who doesn't know what they are or that she's about to endure a life-threatening change—Tasi has no other choice but to follow directions left for her. She is to find an ally who lives in New York City. This is the only way Tasi will figure out why she and Emily are being hunted before they end up drained of their blood.
