Wow this one is so good ㅠㅠ
I LOVE Qifrey and this volume is very much about him so that satisfied me. So much deep development content and I love the bonds being reinforced... until the end. 
Olly is such a sweetheart and good friend. I wish he could have it reciprocated to him. 
I resonated with Coco's stress about there never being an answer. When you're a kid, anything you don't know or struggle with you just ask an adult to fix. But as you grow up, you learn that some things cannot be fixed, or magicked away. This series is so, so good and very meaningful.
