The Vampire's 100-Night Contract

After her werewolf lover betrays her and she is left near death following a fall from a great height, a human girl named Marian is pulled back from the edge by Cillian, a mysterious vampire noble. His help is not free: to gain the strength she needs for revenge, she must sign a 100-Night Blood Contract that makes her his exclusive blood slave. Cillian seems cold and merciless, treating her as nothing more than something he owns under the agreement, yet again and again he shields her from harm and crushes anyone who threatens her.
