This is actually a crowd watch too as Iron Circus is kickstarting a collection of Sophie Campbell’s Shadoweyes: Volume One:

Sophie Campbell began Shadoweyes in 2010. It stars Scout Montana, a slight and fragile teenage girl with dreams of defending her city as a masked vigilante. But one night, close on the heels of her cruelest defeat in the streets, her body inexplicably changes shape, becoming tiny, blue, super-strong, super-fast, and utterly un-human. 

Amazed and intrigued by her powers, Scout embraces her strength and new-found ability to fight for good… but things get complicated when she becomes stuck in her new, monstrous form.
Okay so not quite horror, but monsters and the always excellent Sophie Campbell.
