For me, 55 is a huge amount. My reading life thus far is rather short, and usually I could only finish around 20 books a year. As you can guess, I'm pleased with the result!
I'm not going to try to pick books to make a best-of list because I don't want to have to go through such tough decisions. If you want more details of any of these books, go here.
2011 has been such a great year for me. I can only hope it will get better from now. :-)
