Fear street : Killer's origin

I started a book about the origin of the killer we don't know about, The Grifter, Billy Barker, The Milk Man killer (Harry Hooker) and finally Ruby Lane. It's will see how I think they could be cursed.

It's will have 4 parts, one for each killer.

Hope y'all will like it :) appreciate the reviews that will help me for giving a better story :3
