I DNFd the series - can someone spoil it for me?

Hi! So I finally decided to DNF the TOG series after feeling like I was going to die getting through the tandem read (I stopped around 200 pages into each book). For reference, I didn’t love the other books (except QOS which was AMAZING) but I really did enjoy the characters. My issue with the series is that the pacing absolutely SUCKS - too much of nothing going on, with useless conversations that bored me to death. I think the books all should have been like 400 pages max lol.

Because I have major FOMO and I also genuinely enjoyed the characters, can someone just spoil what happens in the last 3 books? lol like how does it end? Thank you!
