The only thing better than one awesome book is ten awesome books set in the same world... right? Well, not always. Sometimes, the law of diminishing returns kicks in, and the tenth book in a series isn’t quite as good as the first. Which book series did you love—until it overstayed its welcome?

Please include a book cover or other illustration for your chosen book series. And please mention the name of the books, the author, and why you felt they went on just a smidge too long. Thanks!
