I can usually delve into a little heavier reading during long quiet winter evenings. I just finished Sea Wolf, the old Jack London classic. A rollicking tale of adventure among the seal hunters on the open seas. A bit of vintage forgotten history, a philosophical lesson hidden in the plot, and plain fun reading. I'm currently on The Invention of Nature, a historical account of Alexander von Humboldt. There are many landmarks named Humboldt everywhere and I had never known of the origin. Now I know that most of them are probably named for the famous German explorer and naturalist. It's not a tedious read and the cover names it as one of the NYT best books of 2015.
