I saw many people do this and I jumped on the bandwagon too. I started using Goodreads towards the end of 2010 so I thought of listing all the best books I read for every single year of the previous decade. These are not books that were released that year but instead these are just the books that I read for the first time, irrespective of their release date. I am not mentioning rereads in this list.
2010 – Dear John by Nicholas Sparks
I do not have a record of all the books I read this year or the year before this, since I only started using Goodreads in Nov 2010. So I have very few books on my GR list from 2010 and among those, this was the best. My first adult romance novel ever.
