A re-read of Going postal by Terry Pratchett. Wonderful stuff, one of the best of the Discworld novels (although one that depends less than most on it being Discworld).
The Inheritance of Rome: Illuminating the dark ages by Chris Wickham. A really good history of Europe and western Asia, from 400 to 1000 AD.
Wolf Hall by Hilary Mantel. Historical fiction about Henry VIII and that period, told from the point of view of Thomas Cromwell, with the villain being Thomas More. Wonderfully written, and, from what I read in other reviews, historically defensible.
The Great SF stories volume 1: 1939 ed. by Isaac Asimov and Martin Greenberg. I have this whole series on my shelf and I think I will re-read them
Scorpions: The Battles and Triumphs of FDR’s Great Supreme Court Justices by Noah Feldman. The story of Hugo Black, William O. Douglas, Felix Frankfurter and Robert Jackson, and how they worked with (and against) each other on the Supreme Court, which was once described as “Nine scorpions in a bottle”. Only a few pages into it. I am reading this on my Kindle
The Reality Dysfunction by Peter F. Hamilton. Far future science fiction of the space opera variety. Just started.
And some technical books for work.
