Nowadays I mostly read on my Ipad - got a 'library' of a bit over 600 books on it. One of the advantages of my rotten short term memory is that I can read a book and unless it has something utterly unforgettable (About 65 years or so ago read a book in which an American secret agent assassinated Stalin!) I can read it again a year or so later and it will be almost as new.
Pretty eclectic choice, in no particular order - Rebus, Holmes, Sharpe, Reacher, Morse, Hornblower, Vera, Anarchy series, Viking Series, almost anything by Cornwell, Dick Francis, etc, etc. I am a pretty quick reader - average two-three days per book and as I have so much time on my hands now I read a lot to pass the time as well as for entertainment
Mike - and my 'proper' books are mostly non-fiction - military, weaponry, cricket, Rugby, aviation, etc.
