The game processes faster if you’re at a “quieter” location. Don’t read near refugee centers or zombie populated areas. Go in the middle of nowhere, or underground, perhaps. EVAC shelters are pretty nice and remote, too. They have the console for permanent partial lighting but also a guaranteed underground level. You’ll really want your Reality Bubble (60 square radius) to be as free of other creatures as possible. If you’re unlucky though, there are ants on the same level, behind a mass of rocks. Also keep an eye out on the books’ descriptions. Notice the chapter reading duration. Prefer books that are faster to read if at all possible. Plan your reading. Also listen to music to keep your morale/focus up (MP3 players, car stereos).
If you really get sick of reading, just cheat the skills and toss away some food and water to simulate resource consumption. And maybe sleep for a week. I, uhh, I assume skill levels can be cheated using the debugging tools…
Someone might be able to figure out how to reduce the book reading times, by modding and reducing the chapter reading duration, at least for those more demanding books.
I theorize that you would get no zombies or NPCs at all. You would still encounter wildlife though.
