Definitely my favorite Wings of Fire book yet. Glory was always the most interesting of the dragonets. Very defensive and sarcastic, but also carrying the most emotional baggage, from abusive caretakers to not even being part of the official prophecy. Her POV is immensely satisfying.
I also enjoyed that it breaks away from the “go somewhere, get captured, eventually fight their way out” formula of the first two books. The peaceful RainWing tribe is vastly different from the other areas. But we also get brief glimpses into NightWings and IceWings. The overarching plot lays down interesting developments that stay unresolved, but also make getting to the next book even more exciting. And we still get a really fun climax that’s far different than the action-packed endings of the first two novels.
