He told Deseret News in 2016 that Over Your Dead Body was his most challenging writing experience yet because of the "aimless" feeling he wanted the story of John and Brooke on the road to have.
They then move on to their next destination – the small town of Dillon, Oklahoma – and when they arrive, a new personality manifests itself through Brooke: Marci, John's former girlfriend who was killed by the demon Nobody.
This proves to be extremely difficult for him; he is able to talk to the dead girl he loves, but she is trapped in Brooke's body and often gets replaced by the other personalities.
One was the pedophile police officer who was found with Jessica the night of her murder, and Brielle is presented as the primary suspect; John had even heard her vow to kill the predator if he ever did anything to her sister.
He goes to her house, holding her family at gunpoint to get information, but finds Brielle's body in her room, killed the exact way another Dillon citizen proposed.
He finds the demon in a farmhouse outside of the town, mirroring Brooke's inclination to kill herself, and helps Attina start the fire that serves as its suicide.
John loves both her and Marci, tells her so, and leaves the town still unable to forgive himself for getting both girls involved in his supernatural war in the first place.
A San Francisco Book Review writer approved of the continuation of John's story and called the novel "an intriguingly fabulous mix of serial killer horror, supernatural beings, and dark humor.
