These days, there are so many popular book series it can be hard to keep track of what books are coming out when, and what order to read them in! Summer is a great time to crank through a series.. And the What’s Next Database by Kent Public Library in Kent County Michigan is a great resource for readers of any age looking for a series of books to crank through! If you know the series, you can search by book title or author name. If you’re looking for a new series, just check off the genre and category (age) of the books you’re looking for, and search away!
