When Special Agent Jack Mills of the National Clandestine Agency receives a call from an old partner, he is drawn to the small rural community of Whisperwood to investigate an unsolved murder from his past. Aided by his new task force of monster hunters, Mills must return to familiar paths fraught with peril and painful memories, leading him to Holbrook House--a mysterious ruin possessed of something not from this earth.
As the danger mounts, Mills seeks the aid of author and paranormal investigator, Bob Freeman, to unravel the mystery surrounding Holbrook House and the cult that has come to offer sacrifice to its new otherworldly occupant.
Finally, the veil between worlds is torn, unfathomable abominations emerge, and no one is safe within Whisperwood.
