This seems to be the year for authors writing unexpected sequels to extremely popular books. I have Lauren Weisberger's Revenge Wears Prada sitting next to me as I type, and I am already on the waiting list for Stephen King's Doctor Sleep. I tend to prefer standalone novels, especially given the agony of watching people wait for the next book in George R.R. Martin's A Song of Fire and Ice.
Here are some blockbuster books with sequels coming out this year. Be sure to refresh yourself if need be!
Do you tend to read standalone books or series?
