Star of the North (2018) by D.B. John

This is a novel about three lives that intersect in the US and North Korea. It's a great read. It's fiction but really seems to paint a true picture of life in North Korea.

For Love of the Game by Michael Shaara (1991)

Story of an aging pitcher who pitches a no hitter just before he's traded/ thrown away. It's written well, good subject.  Go for it.  There is also a starring Kevin Costner which is based on this book, and is also worth seeing.
