I too value the breadth of reference on here - although, for e.g., I wouldn't ever pick up a fantasy novel, I do just like hearing what other people think, expressed in witty and interesting ways.
And in that spirit, there are probably plenty of you who wouldn't want to go anywhere near my latest read, which nevertheless is probably my top book of the year so far:
34: Waterloo: The Aftermath - Paul O'Keeffe
This is simply fantastic. It's been on my wish list since it came out, in the run-up to the bicentenary of the Battle of Waterloo. O'Keeffe draws on a huge range of eyewitness accounts of the battle, but more importantly the days and months immediately afterwards. The sheer visceral horror of hand-to-hand combat and the appalling injuries (he includes testimony from battlefield doctors and surgeons) is gut-wrenching, and the story of the French retreat and the terrible fate of the wounded - both men and animals - comes vividly to life.
Just as fascinating is what happened to Napoleon once defeated...I didn't know that he'd attempted suicide by poisoning (an antidote was administered) or that he'd hoped to be allowed to settle in America or even England (!), before being exiled against his will to St. Helena. For anyone interested in history this is a superb read, and written in brilliantly readable style.
(Just on a personal note - I couldn't help finding the fate of the poor horses particularly distressing, but I've discovered that a local landowner actually bought a number of wounded Waterloo horses and had them shipped home to England, where he nursed them back to health and let them live out their days on his estate, which is now a park I pass by most days. There's something very heartwarming about this...)
