The Glass Beads Game by Herman Hess.
Several books by Steinbeck - Travels with Charley, Log from the Sea of Cortez.
The Toilers of the Sea by Victor Hugo. A recent penguin translation is superb. Among the saddest and most memorable love stories.
I also recently read Kafka's The Trial, which I've long known about but never read, and it was good but not at all what I expected. For some reason I expected Kafka to be an intimidating, serious writer, based on how his name has come to be used metaphorically. But The Trial is a very easy read, engaging and plot-driven, moving along at a fast pace. You can read it in a few hours, and it feels like light reading, despite having some serious content.
