I think that you should throw in some variation to your sporting books. Perhaps a thriller or two if that's your thing. Something by Harlan Coben, Linwood Barclay or Robert Goddard would fit the bill. Maybe look to get some historical books too, something about WW1 or 2 or maybe even some historical novels. There's a few to choose from about The Roman Empire or perhaps The Peninsular War. Simon Scarrow's Wellington and Napoleon trilogy is excellent reading and informative.
One thing worth having is a Kindle, even if you don't normally use one. If you can't get out, you can download books off the internet without even having to wash your hands!
