We love these Halloween decorating ideas from Real Simple. We also recommend decorating your bookshelves this Halloween with spooky novels. Here are a few titles from the adult fiction section with spookiness that extends beyond the cover:

The Hatching by Ezekiel Boone. This book is full of spiders. However, it is also a rolicking Jurassic Park-level adventure. Creepy fun.

Dark Matter by Blake Crouch. A physicist wakes up in an alternate reality. Fans of his novel Pines or the tv series Wayward Pines will enjoy this tale of timelines gone amok.

A Head Full of Ghosts and Disappearance at Devil's Rock by Paul Tremblay. Fresh takes on exorcism stories, with transcriptions or journal "pages" to lend a sense of realism.
