[Kaderin Triste]

There is nothing wrong with rereading boijs that you enjoy!
It is good to mix it up with new ones occasionally though.

Honestly, I almost never read non-fiction books. Probably because of being forced to read dull autobiographies in grade school. Plus history, which generally was such a broad spectrum that we would literally spend half the year on the same things we always covered and barely skim anything interesting (literally any world history OUTSIDE of the U.S.). I have found the historical fiction novels of Erik Larson to be fairly interesting, if a bit on the tedious at times.
Correction: apparently his novel The Devil in the White City is just considered true crime by Barnes and Noble, so his other novels are probably just considered histories. *shrug*
