Writer Wednesday: Books/Series That Change POV

I recently started reading a book in a series that I quit reading years ago. Why? A few years ago, my husband bought me the latest book in this series as a Christmas gift. At the time, I thought I wanted to read it. But after book six or seven, I couldn't take the series anymore. And the big reason was the POV. It changed out of the blue. I don't like when a series begins with one MC narrating and then all of a sudden three or four books in, we have multiple narrators. I've never understood this. I get attached to the POV and I don't want it to change.

But I've had this book on my shelf, and I felt obligated to give it a chance. After all, I liked the first three books in the series (before the POV change) and I thought now that time had past, I'd be more open to giving the series another try. Well...I'm trying. I really am. But I find myself cringing when yet another POV is introduced. A minor character's POV. I'll be the first to admit that seeing a scene from another character's POV can be interesting. It offers new insight. But I don't want to be inside every character's head. It's too much. I feel like I know everything that's going on and the poor MC is clueless. I'd rather discover things alongside her.

How do you feel about books that introduce a new POV late in the story/series?
