Ghost Killer Collection

All three books in 'Ghost Killer', a series by Margaret Millmore, now in one volume!
What Haunts Me: George is plagued by strange dreams - nighttime visions of ghosts who wander among the living and infect their victims with deformity and disease. A deeply buried instinct emerges: he can kill these monsters and heal their victims. Haunted by suppressed memories, George's sanity begins to slip away as he becomes consumed with his new responsibility. This dark and dangerous path will lead to new friends and allies, and enemies George never could have imagined.
The Edge of the Cemetery: George works alongside his new friends and assists 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, the Watchers know it isn't a random occurrence. As George and the Watchers investigate, they discover that a demonic presence is behind the attacks. With the clock ticking against them, they must find the source of the evil and destroy it, or risk extinction of all humankind.
What Hunts Me: In the attic of the large Edwardian house in San Francisco owned by the Watchers, a box is discovered. In the box are various documents of ghost killers and a diary that chronicles an epic journey from Pennsylvania to San Francisco, along the route of the newly opened Lincoln Highway. Strange drawings and nonsensical writings in the diary tell of something sinister. George soon travels to San Francisco to investigate, and the more he learns, the clearer it becomes that something horrible happened in 1915. A monstrous creature has reanimated, and it is searching for something. As supernatural forces come into play, George and his friends are propelled into a fight for their lives.
