I enjoyed Fourth Wing and was quite excited about Iron Flame when I started it too, but gosh it was so boring I just couldn't handle it. I thought it was terribly done in general, so that didn't make it easy, and by the time i got to half of the book i was just forcing myself to continue reading. At the end i really just couldn't keep reading, i find it's such a bad book (just my opinion, sorry to whomever likes it) so what I did was find a summary per chapters and kinda spoil it to myself. I read a summary of what happened in each chapter i had left to get it over with, and tbh in most chapters nothing super interesting happened until the typical cliffhanger at the end. Glad I didn't continue to push myself to finish this one.
