Day 26: Favourite nonfiction book.

Mmm…I don’t usually read a lot of nonfiction, unless it’s essays about fiction and fictional things.
Two favourites I can think of atm are The Marriage of Cadmus and Harmony (based on the sheer number of times I mention that book, you should know by now that it’s worth a read), and J.R.R. Tolkien: Author of A Century.
