H.D. Carlton is known for writing risky and controversial dark romance novels, the most notable of which is her Cat & Mouse Duet. Though Satan’s Affair is a spin-off of the Duet, it overlaps directly with the events of Haunting Adeline, the first novel in the series. When Adeline goes to Satan’s Affair with her friend Daya, Zade follows them and encounters Mark Williams, a senator involved in a dangerous child-trafficking cult known as Eternal Rebirth. Mark wants to kidnap Adeline for trafficking, and Zade steps in to stop him, while also finding out more about the cult. Sibby, a young woman who lives at Satan’s Affair, tries to stop Zade, thinking he is another abuser, but they end up working together to take down Mark and his associates before being split up by the police. Satan’s Affair is often listed as the first work to read in the series, but the tertiary nature of Sibby’s involvement in Haunting Adeline establishes it more as a companion work than a strict prequel or sequel.

The Cat & Mouse Duet is known for dangerous and often disturbing sexuality, which pushes the boundary of fantasy and sexual assault.
