What is in your opinion the best moment in the books?

Ive read up to volume 10 audiobook and book and so far, its been one of the best fiction ive ever consumed. (spoilers for book 9, uve been warned)

To me, the most impactful moment was end of volume 9, the fights against Cadell. It just felt like so much, since book 8 especially, Arthur has been building up his strength and through all the books, it feels like it leads to this moment. Not to mention how epic the actual fight was (engtrance, everyones shock, fight, escape, everything) I just feel like it was so perfect.

Because I feel so passionate about this part of the story, I also wanna hear your favorite moments in the series. Please, do share yours.
