What are your favorite books for Kindle?

Dave

Being an avid reader Marion bought me a Kindle 3G for christmas 2010.  She thought this would be a good idea because the previous year I took 28 books with me for a 4 week trip and ran out!  Whilst it's fun to swap books with other people you meet whilst
touring France  the kindle is much easier to use, restock and saves on a lot of weight and locker space.  I read most  any and every thing. To date some 185 books are listed on my kindle archive and growing at a fast pace.  Some I've read more than once! 
So people what do you think of them and what are your favourite books?
