I really don't read that many series - the only one that comes to mind is Diana Gabaldon's "Outlander" series.If you read series, do you ever find a series “jumping the shark?” How do you feel about that?And, do you keep reading anyway?
I read the first two books in the series - Outlander and Dragonfly in Amber when I was around 16/17 years old. I came back to them in my mid-twenties and at that point Diana had gotten ahead of me with several more books in the series. I think I read the first four all in a row and then started on the fifth "The Fiery Cross." In my opinion, that whole book was a jump the shark moment for the series. Long, tedious descriptions of community gatherings and extended examinations of Roger and Brianna's relationship. To make matters worse, the series did not seem to be moving forward at all! I stopped reading about 100 pages in and haven't returned to the subsequent books in the series.
I've since heard that many people felt that way about "Fiery Cross" and have improved opinions of "A Breath of Snow and Ashes" and "Echo in the Bone." At some point, I may return to those books but it would take a lot to get me back in with "The Fiery Cross."
