Books that involve an entire community/town

I’m looking for books that do a good job of showing how an entire community is affected by whatever horror/terror is happening in the story. Salem’s Lot was pretty good at telling us about people in the area that were equally at risk as the main characters. It doesn’t have to necessarily go into detail about everyone but just reminding the reader that a lot more people are at risk outside of the main characters.

Edit: Oh damn! I’ve been at work so I just saw all the replies, thank you so much everyone!! I’ll definitely be going through all the comments and suggestions ✌🏽
