His Crimson Devotion

Amnesiac Vivienne believes she is the pampered fiancée of Damien, a centuries-old vampire lord who serves her every whim and nightly feeds her a strange "medicine." Finding bite marks and his lack of reflection, she thinks she's a monster's blood-slave and flees—straight to Elara, a ruthless hunter who covets Damien's heart and turns Vivienne into bait for a silver trap. But when the arrows fall, Damien shields her with his body without resistance. Seeing his wounds and the vials of life-essence he drained from himself to keep her alive, her memory returns: she stayed for love years ago, and he spent his own immortality to save her. As he lies dying, she presses her bonded blood to his lips—no longer prey, but the one who will awaken her vampire lord.
