That book was really interesting! I loved the Snape-like character of Nalizar. Joel suspects him the entire time, so I thought that he is for sure innocent. But then, twist! He is even more dangerous than I thought! The interaction of Melody and Joel are so interesting, too. Melody is such a colorful and emotion-driven person, while Joel is the more steady and logical person, though he is kind of gray. In my head they are headed straight towards a romatic relationship, but I see that other people are interpreting things differently (which is a valid view too). Their unofficial date was indicating to me that when other poeple see them as a cuple and none of them is activly denying this being a date, they have already moved on from platonic friendship. But of course this is just a try-out phase and they could go back to platonic friendship or move to romatic relationship from here.
One weaknes of the book, that I imediatly noticed was: Rythmatists have ankle-length cloaks. That would be super inconveniant when kneeling on the floor and thrying not to smear your circle of warding, while drawing chalklings and lines of vigor. I think, instead they should have official knee pads. Especially the older Rythmatists.
All in all, another Brandon-style genius book with lots of suspens, interesting characters and plot twists. Absolutly loved it.
