The Edge of the Cemetery is book 2 in the Ghost Killer Series, and although it could be read as a stand-alone novel, book 1 was developed as an introduction and I would recommend starting there first. Below is a more detailed description of the continuing adventures of the Ghost Killers - I truly hope you enjoy this new series!
There are ghosts and demons that wander among the living; they do not haunt in the traditional sense. Instead, they plague mankind with diseases and physical deformities, and once a ghost finds its victim it will haunt them for a lifetime. When George Sinclair discovered he could see these ghosts, and more importantly, he could kill them and save their victims, his life changed from ordinary to extraordinary, he'd become a ghost killer, one of the most powerful to be born in some time. George has embraced this new life and now works alongside his new friends, Billy Wilkinson and Phil James. Together they assist the Watchers, an international group of ghost killers and supernatural experts who monitor the world for ghostly sightings and demon infestations to maintain the balance between the living and the dead.
When San Francisco and the surrounding area are suddenly plagued by rogue groups of ghosts and demons, who appeared to have a leader of sorts, a 17th century musketeer demon, the Watchers know it isn't random, nor was it the usual form in which ghosts and demons prefer to haunt. These monsters were also possessing their victims and forcing them to hurt others, and once the ghost killers arrived, the demons directed their human weapons on them. The question was, who was this musketeer demon and why was he directing these attacks?
As George, Billy, Phil and the Watchers investigate, they discover the 17th century demon is teamed up with a teenage boy, who they come to realize is a powerful ghost killer himself and more importantly, they believe he is being controlled by the demon and is now using its energy to kill people at will. Their search for the teenager and his demon lead them to the discovery of an enemy from their past and a mysterious prophecy. As they decipher the true meaning of the prophecy, they uncover a plot for murderous revenge involving a secret vault containing numerous malevolent souls and a plan to return those wicked dead to human form as directed by Satan himself. Unfortunately, they also discover the true purpose of the demon musketeer's involvement, which is to become one with the powerful teenage ghost killer, creating a monster that cannot be defeated. With the clock ticking against them, they must find the vault and destroy it before it can be opened and kill the demon and his teenage host.
