I haven't really looked at my entire history of Gamelit series in a while, but I'd say this is shaping up to be a top 3 reading experience.
It's a bit of a risk to add a magical school arc midway through a series, especially since it's a bit of a cliche to do so, but here it's merely a subplot that's part of a larger story flow so it works. Generally, it would be hard for me to care much about adolescent concerns about school life after a character has successfully led a rebellion and established a sovereign nation, but luckily, the focus is on other things rather than childish social squabbles.
The romance subplot in this book is fine I guess, though it seems like it came on a bit strong and quickly. Honestly, I don't know that any gamelit is going to do romance well for me because that's not what I'm here for. Best case, it contributes nothing to my experience, and beyond that just risks distraction or displeasure. It's only a minor annoyance in this series since the romance characters actually serve purposes to the story other than merely checking a romance box on a trope list.
The author continues to do a great job balancing the power curve. Despite how OP certain characters seem, there always seem to be checks and balances. I can't wait to see where the story goes after we wrap up the school business and get Viv's mana poisoning taken care of.
