First of all, I love the concept of this. I wish more short story anthologies were more collaborative stories like this because I feel like I'm more invested. I also think teens would be more drawn to them than the regular short story anthologies that are being published (of which there are too many in my opinion, but I digress!).

My main issue is I think there are a tad too many characters in this one. There's a lot to remember between the stories, and widdling it down to fewer authors (which means maybe they get to write more parts?) would help with the overall clarity. And maybe a character map if you're going to have this many characters.

The mystery intertwined with the fantasy though, I enjoyed that! I loved the magic school setting, too. Such a fun concept that just needs a little bit of tweaking to really put it over the edge.
