What Haunts Me by Margaret Millmore

After George gets ill, the dreams begin. Suppressed memories surface, allowing him to see ghosts, and a deeply buried instinct emerges.

George finds out he can kill these monsters, and heal their victims. The ability to save lives is something he cannot ignore, but it soon becomes an obsession and begins to eat away at George’s sanity.

His quest for understanding leads him to new friends and allies, and exposes him to enemies he could have never imagined. But how do you kill something that’s already dead?
