Spooktober is here. Looking for two suggestions: 1. Book that will scare the pants off me and 2. Cute halloween/autumn vibes

Like a mix so want one horror book and one cute halloween/autmn book.

Horror:
Just something that will genuinely scare me. Only rule is no animals being hurt and no graphic descriptions of touture like toenails being pulled out.

Cute:
Something with autumn vibes. Could be a cozy mystery, kids going out on halloween night. Thinking something like over the garden wall or a bobs burgers halloween episode.
