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?
The way my brain works if I don't like a book I tend to repress the memory of that book. So my mind is drawing a blank with this question. However I have read some books in a series that I suspect the author may have had an “off” period. Usually the next book more than makes up for it. My favorite series of books is currently anything by Laurell K Hamilton. All of her books have kept me interested.
