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”.
Aside from Discworld which really is a fantastic series, I’ll recommend The Dresden Files.
It has a slow start IMO but once the edge wears down and Butcher just lets himself nerd out it’s just such good modern fantasy
