Winter 1964. After a hit-and-run accident nearly kills her mother, Mike Hammer's partner (both in life and the PI business), Velda Sterling, learns her father is not who she thought he is. Seeking to uncover her true, troubling heritage, Velda and Mike travel to Phoenix, Arizona--and sunny Dreamland Park, where retired law enforcement officers protect and corral notorious criminals held under Witness Protection.

Mike and Velda find themselves swept up in escalating violence, fueled by the missing millions from an armored-car robbery, which leads them to a deadly midnight confrontation in a cemetery--where secrets are buried and open graves await.
