The Monstrumologist - Rick Yancey
This young adult book is so well written and frankly, disgusting, that you will think it was written for grownups.
The Shining - Stephen King
Haunted hotels, axes, potentially murderous fathers?! This book has it all and more - the king of horror will keep your book club talking for hours.
Slasher Girls and Monster Boys
This collection of short stories is so well written that I found myself saying What the hell several times throughout the book. Your book club will love it.
Survive the Night - Danielle Vega
What do you do when you get back from rehab and your old friends invite you out to an all night rave? Go, then spend the rest of the night running from a murderer while in an unused subway station. This is one book your book club won't be able to stop talking about!
It - Stephen King
Stephen King is so good at scaring the crap out of people that he's on the list twice. Reading It will give your book club plenty of scares and so much to talk about.
