Pretty derivative YA. Feels like the kind of story written by 14 year old girls. Id have loved this at 14, but alas I'm an adult who's read many books just like this so I was bored.
Mainly I found the set up of a school/society where its acceptable to kill your fellow students whilst trying to train you for war where trust is a big part of holding your squad/team together nonsensical. I found the drama mined from this premise eye rolling at best. If youve read anything by Sarah J Maas, this is mostly the same vibe but with dragons, and less well defined characters. If you love that you will probably love this, but it's too juvenile for me.
