What were your favorite books of 2016?

It's that time of year again and we only have one (very busy) month left in 2016, so while we are thinking about our 2017 challenges and reflecting on 2016...

What books did you enjoy the most in 2016?

Did anyone read a book so thought provoking that you lost sleep over it? In a good way that is.

Or maybe you read a horror book so terrifying that you now need a night-light?

Which books did you play hookie for?

What books did you read that will go back into your to-be-read list?

Also, which books published in 2016 stood out to you? What are your early favorites for the __________ Award?

Here are the last few years posts for reference:
