I started reading “Tropic of Cancer” recently, knowing nothing about it except that it was supposed to be a literary classic. I assumed it was going to have a plot, but... it totally doesn’t! It’s just kind of the diary of this sleazy dirt bag living in Paris during the Great Depression. I feel kind of gross reading it, but something keeps drawing me back to read a chapter every day or two.
Before that, I read “Living with a Seal” (some good light reading) and “Sapiens” (pretty heavy, a condensed version of human history). Those are two books I could recommend without reservation.
