There is a long-held belief that it's always best to read the book before you see the movie. The theory may continue to hold true heading into 2018, with several book adaptations into feature-length films.

Books remain popular gifts and the number of books sold has increased. According to Publishers Weekly, print-book sales rose 3.3 percent in 2016 from 2015, making it the third-straight year of print growth.

These highly rated books could be great stocking stuffers.
