just finished the book that wouldn’t burn by mark lawrence and really enjoyed it, but I have some questions about the rest of the series

I am going to read the rest of the series soon but as I tend to read at work, I have questions.

what are some sad moments in the next two books?

does wentworth die?

do arpix/livira die?

and just in general, how did you feel the next two books compare to the first? I find usually the second or last book in a series are the best, how would you compare them?
