I remember a book I read in middle school (80's-90's) about werewolves. It had drawings in it in black and white and I remember one of the drawings was a bunch of slaughtered pigs and even a pig head on a stick or something along those lines. I think another one of the drawings was of the werewolves inside a church. Anyway I remember it was a small book from the 80's or early 90's and the drawings were very scary and I'm not sure about the plot of the book, I think it was just the descriptions of the werewolves and how they transformed etc. Maybe there were stories that went along with the drawings. If anyone remembers or knows anything about the book, I'd appreciate it!
