I want books similar to Ten Days Until the End. I am a seasoned horror reader, but lately I don't know what's wrong with me. I can't get into anything, so I sincerely ask for recommendations for terrifying and suspenseful novels, preferably narrated by real people. Unlimited-flow, eerie mysteries, rules, post-apocalyptic settings, and so on are all fine! I don't like mindless power fantasies with live comments, livestreaming, or national luck.
