TES books are the best, dude. I'm playing a (heavily modded but largely vanilla+) playthrough of Skyrim right now and just came across a large trove of tomes. I grab whatever I come across that I haven't read while in dungeons or what have you, and at night when I return to my campsite (Campfire mod) I like to gather wood, roast a meal, and sit down to read through whatever literature I found that day. I have a stash sack full of some too for those nights where I'm feeling too wiped to really get into the game. I can just relax to the sound of crickets or morning birds and catch up on my lore.
