Killer Lake by David Benton and W.D. Gagliani

Recipe for a Satanic panic:

Take a medium-sized cult and their best demonic summoning. Mix with a dash of strange psychic powers. Generously add murderous reanimated corpses, inbred cannibal rednecks, sex-starved half-naked coeds, horny football players, and a surprise creature or two. Sprinkle in a fancy log cabin mansion, a labyrinthine set of tunnels, and a secret ritual chamber. Stir. Bake on high at 666 degrees.

You know it's gonna be one killer party...NOMINATED FOR THE SPLATTERPUNK AWARD (2020, Best Novel) and for the INDIE HORROR BOOK AWARDS (SPLATTERPUNK)!
"[Killer Lake] was awesome...if you're a fan of Edward Lee and Richard Laymon you may really, really dig this book!"
--Paperback Mania (YouTube review)
 
"Rosemary's Baby meets Texas Chainsaw Massacre! Deadly rituals, a secret coven and a cavalcade of unclad co-eds. Killer Lake is a devil of a good time!"
--John Everson, author of Nightwhere, The Devil's Equinox, and Covenant
 
"Many of the classic tropes and archetypes--jocks, sluts, the nice girl, the rich boy, the bad boy, the misfit, the alcoholic wreck of a professor, the bumbling country cop--are well-represented, but with some surprising twists... Entertaining, fast-paced, splattery, shameless, lowbrow and delightfully trashy. I read the whole thing in one day..."
