Halloween's about dressing up and eating candy (and, for many adults, getting incredibly drunk). But that doesn't have to be all it's about. Back in 2010 Neil Gaiman suggested a new Halloween tradition of giving away a scary book to a friend on that most spooky of holidays. Since then that basic idea has evolved into All Hallow's Read, and we here at The Mary Sue are supporting it by highlighting eight of our favorite literary horror heroines. All of the books we’ve mentioned here—including one by Gaiman himself, which is only fitting—come with the TMS stamp of approval if you want to participate in the AHR tradition of book-gifting.
