Well having read less this year it should be easier to remember what I liked.
The best fiction has several competing titles but as a very different book I think it should go to: “The Guernsey Literary and Potato Peel Pie Society” by Mary Ann Shaffer and Annie Barrows, the style of writing used bought different angles to the tale.
Best work related goes to: Alex (Sandy) Pentland’s book “Honest Signals – How They Shape our World“. I’m still turning over sonme of the ideas from that.
Best non-fiction is: Levitt and Dubner’s “Superfreakonomics“, it’s so full of interesting things!
