Suggest me some really good books, either niche or not so niche, for someone who needs to maintain their recently adapted reading habits.

So I (20M) only just started reading again back in September. I've kept a good pace of about a book or two a month. Since I started, I have read 4.5/6 Red Rising books, Misery by Stephen King, Project Hail Mary by Andy Weir, and Watchmen. All of these books have been wonderful, my favorite of them is either Golden Son (Book 2 of Red Rising) or Misery.

I'm totally open and interested in literally any genre, themes, or setting, but preferably something more for an adult audience. Lately, I've been a little more interested in reading another horror novel, but any recommendations are appreciated
