Blood Contract

Rosy loses her job and drifts for a while before she meets Sam, a wealthy vampire who offers to pay her to be his wife under contract. She is frightened of the world he comes from, but she takes the offer because she thinks it is her last chance to put her life back together, and she moves into the family manor. Once she is inside the house she learns what the contract is built on: blood oaths, forbidden rituals, and a succession fight. Sam's father, who ran the family without mercy, is dead, and Sam and his younger brother Ken are both trying to take the family business. Rosy works out that she was never brought in as a small piece of the arrangement. The blood pact is written around her, and it can kill her.
