I have high expectations of it as I always do with Dana's works (and she never dissapoints!)
What excites me the most about the story is how the post-belos world building will get presented, I'm genuinely intrigued how everyone in general is dealing with the trauma of surviving a post-apocalyptic world, the grief for what was took from them (freedom, magic, friends), and maybe a emotional numbness that might come after realizing everything the emperor coven made them believe was not real. I have already two toh fanfics that touch the surface of this already (with blight family and boscha) and i hope i was able to get it right.
Also i think not a lot of people expects this from me but the owl family dynamic is my favorite from toh, and it is truly strikin for me to see how are they going to solve this without Luz, being Luz herself the one that needs help here. I think it holds so much value that now Luz is unable to have her consistent leader role and she will experience in first hand how other people will do everything they can to help her (I'm also curious for HOW MUCH will she forget bc on that depends who is gonna get involved in her recovery too).
And of course, I'm just generally happy to see my fav characters again. I miss my hexsquad SO MUCH, i miss my blight siblings A LOT. What can i say, i'm just excited about my fav cartoon media ever.
