Re-reading Anathem by Neal Stephenson, because it's so god damn good. The Mandibles recently. It was okay. The economic ideas were interesting, but the story dragged. The Accusation by Bandi was good if you like North Korea stuff. The Rise and Fall of D.O.D.O - Was decent for a Stephenson novel, but definitely niche sci-fi/fantasy. The Glass Bead Game by Herman Hesse. Didn't like it. Really didn't like the ending.
