Well, not really "the best" but just the ones I saw. This is the season when everyone has posted their "Best Book" or "Favorite Book" posts detailing which books they read which were their favorites of the year.
Here is a collection of what I have come across this year. If I have missed yours, or if you know of some others I should check out, please let me know.
(In no particular order other than the order the tabs happen to be open in my browser).
