I think this is the book with the densest dialogue in the series. That is, on 200 pages, you are having difficulty concentrating with "What's happening, stop, why did he do this".
I also think I'm a bit bored. If there were only 2 books left until the end of the series, I would have given up.
Anyway, we will finish it now :/
The book in question seems to be overly focused on dialogue, which can make it a bit of a struggle to stay engaged. The constant repetition of phrases like "What's happening" and "Why did he do this" can become tiresome after a while. It's understandable that the author might want to create a sense of urgency or mystery through the dialogue, but perhaps a more varied approach could have been taken.
The fact that the reader is already considering giving up on the series with only a few books left is a sign that something might be amiss. However, it's also possible that the story will take an unexpected turn and redeem itself in the end. Only time will tell if this is the case.
