What do you like reading about?
Personally I like reading racers auto/biography's so I tend to buy them when they come out ... (got every one that I know has ever been produced (in the last ~10 years)).
I don't know how technically minded or technically curious you are, but I have also read a few 'how it works' type bike books ... I've read the full John Robinson line ... i.e.

Great books, bot not exactly light/bedtime reading as you have to think a bit
so again depends on what you want from a book!! ... if it is entertainment or learnin'
