The Vampire's Rare Blood Maid

When seventeen-year-old Eleanor discovers her parents plan to sell her permanently to a vampire on her eighteenth birthday, fate intervenes—she's purchased by the ancient vampire Sebastian Astoria.
For ten years, Eleanor has been forced to provide blood to vampires, treated as nothing more than a commodity by parents who deemed her "evil" from birth. But under Sebastian's protection, everything changes. In his mansion, she learns she's a rare dhampir (half-vampire) with extraordinarily valuable blood, and as his servant, she finally experiences respect and kindness.
Boundaries between master and servant begin to blur. Her quick wit and compassion awaken something long dormant in the ancient vampire, while his protection offers her the first taste of safety she's ever known. But can a servant girl truly trust the promises of a creature who has lived for centuries?
