RIP vol. 1: Choices After Death
Ghosts are people, too, but not all ghosts choose to be good people.
Rip Cooper must overcome his fears and kill dead people to prevent them from corrupting the living. This young loner learns he can perceive ghosts with his five senses as if they were flesh and blood, and he's just as solid to them -- pretty much the only solid thing, in fact. He works alongside an impure "angel" and his ex-best friend's ex-girlfriend as they teach him how love can lead to strength.
RIP vol. 1: Choices After Death features the first four novelettes in this coming-of-age and redemption story: "Touch," "Alone," "The Crazy Line," and "Point B," plus the short story "Strength."
