Obviously, they don’t have to slide into the cozy genre. But what books do you cuddle up with during a thunderstorm, or your variable weather of choice? Personally, Becky Chambers has become one of my favorites. I also read LOTR when I need a “good guys doing the right thing just because it’s the right thing to do”.
Just about anything from the Discworld series by Terry Pratchett. Clever, insightful, delightfully sarcastic, but never mean-spirited.
And no matter how many times you re-read them, you always find something new.
