Here you can read about all the books I have personally found interesting, thought-provoking, informative and simply a pleasure to read.
As Christmas approaches it would be prudent to start the pedals turning with my own '12-days-of' list. In no particular order - a futile endeavour anyway - with a few more books sneaked in here and there -
Christmas 2013 - if you have been a good boy or girl I suggest you write to Santa asking for one or more of the these:
1. 'Need for the Bike', and 'Velo', by Paul Fournel, 2003
2. 'The Rider,' Tim Krabbe, 2002
3. 'The Escape Artist,' Matt Seaton, 2002

Hope this gives you some ideas, it is by no means definitive and I have omitted many excellent tomes. What you have above are some books that I enjoyed - for a variety of reasons.
