There are no spoilers in this, so don't worry! :)
I just finished ACOSF and WOW. I'm a catatonic, sobbing mess to be honest. Sarah continues to do incredible work. This new insight into Nesta's character was very welcomed-- I never like how I portrayed her in ACOBAN, but didn't have enough understanding to do much with her.
This is honestly making me consider redoing ACOBAN (yes, a third time) with better insights into each character. Revamping the plot into something useable, maybe even something completely different, and committing to it. It won't be a top priority-- I still have my original works to think about-- but even just updating it a month at a time would be something. I know people are eager to have it back.
But yeah, incredible story.
