The main character's name is Seth. Or Tyler. Or Marvin. It doesn't matter because he works for Family for Rent. Seth becomes a brother, Marvin becomes a father, Tyler becomes the son of the sick and unhappy Dorothy Balmont. In the world of lonely people, what everyone has been waiting for happens - the Langot corporation, thanks to Dr. McCaleb, erases any memories, making people happy. No one else suffers. But Del Simmons found a different use for Langot. He turns to Seth with an offer to become the lover of Catalina, his own sister, who cannot recover from the death of her parents. Would you erase your memories if given the opportunity?
