There are few books I've read more than once, but three of them are by Judith Sonnet, including this double feature with a sick cover by Don Noble (the third being Summer Never Ends).
Blood Suck and Zombie Vomit Shitshow are perfect examples of the extreme horror genre, with a gritty atmosphere, gore, ungodly violence that just keeps getting worse, and dark humor that's surely damned me to hell. This double feature checks all the extreme horror boxes.
So, if you want to find out how to entertain your redneck friends with a toothless chained up Zombie or you want to know how Roxy and her friends use their talents to make a little cash, check out Blood and Brains. What’s better than Zombies and Vampires for the spooky season?
