Highlights
Non-fiction
Against Intellectual Monopoly has a couple of flaws: it's a little strident and a bit too dense to read easily. However, the content is enough to make it the book of the year. Written by actual economists it makes a powerful case, backed by extensive evidence, that copyright and patent are economically and creatively harmful. While that's widely believed, it's rare to see it so convincingly argued.

Also notable: John Keegan's impressively broad A History of Warfare, and modern stoic book A Guide to the Good Life.

SF
The Gone-Away World is an entertaining, well-written debut post-apocalyptic novel. Otherwise it's the usual suspects: Joe Abercrombie's Best Served Cold continues with his bloody action-packed dark humour.

Lowlight: made the mistake of struggling through to the end of Stephen King's Dark Tower series: gets worse with every book as it staggers towards a dire ending. Wherever you are, bail out now.

Other fiction
Sadly, finished Patrick O'Brian's superb Aubrey/Maturin series of sea novels, but the last few aren't quite up to the early ones. Doris Lessing's Eighties classic The Good Terrorist was a great read. Winter's Bone has a great evocation of impoverished Appalachian life, and The Damned United was a fascinating psychological study.

Comics
Nothing of real note this year, apart from a re-read of Watchmen.

Well, that about wraps it up. See you in 2010!
