Vow of Blackthorn

Eleanor Thorne is out of options. To save her dying father, she signs a one-year marriage contract with Silas Varen, the reclusive lord of Blackthorn Manor. But Silas is a vampire—and Eleanor is not just any bride. She is the half-blood heir his enemies have hunted for centuries. As forbidden desire becomes a bond neither can deny, a hidden blood relic, a ruthless uncle, and an ancient war threaten to tear them apart. When the year ends, Eleanor must choose: return to her human life, or vow herself to Silas forever.
