If bunker short to medium term situation, prob a scifi shelf. If long term, probably the math shelf.
Not familiar with Sanderson, which appear in large quantity. Any good?
Discussion
Sanderson is a prolific and entertaining fantasy author. We have a lot of them because he writes a lot and my wife knows it is a safe gift. I question whether his writing will be remembered long term though.
Got that impression after looking him up. Sure it’s decent, but never read much fantasy
