We are doing this in October. October has 31 days but the challenge only has 30. And the challenge has no category for scary books. What better day could there be than Halloween to share favorite scary books? So I am adding an extra day to this challenge on the 31st: Day 31 - Favorite Book that Scared the Snot Out of You. At least for myself. I hope a lot of people join me because I really want to know your favorites in this category.
Edited because I had a really stupid typo in the title.
