I've been thinking back over the books I have enjoyed in the past to think which of them needed a sequel. Here's what I've come up with:
To Kill a Mockingbird: It would be nearly impossible to match the voice of the original, I know, but I would love to see what happened to Scout as she grew into an adult.
I thought of one of my favorite books, Little Women, but that's been done with Little Men. And, I discovered something I didn't know... there was also another sequel that follows the sisters---Good Wives. AND, I also discovered that you can get all four books in the Little Women series for only $0.99 at Barnes and Noble or Amazon.
Most of the book I enjoy are already series: Anne of Green Gables, The Chronicle of Narnia, JD Robb's In Death series... I tend to binge read as much as I binge watch. You can see other series I love here.
But that takes us completely off-track... books that need a sequel.
There was a book I loved that had a sequel... and it needs another one because the sequel was less-than-inspiring. I wish someone could write a good sequel for Gone With the Wind.
What about books you have read? Are there any you think could use a sequel?
