I'm intrigued enough by the ending of this volume to keep reading to the next volume, but I'd put this book in the kind of limbo where if the payoff to what this book sets up is too weak, then it could sour the whole run.
Very visually stunning final installment to the manga - with a lot of expansive vistas (and a penultimate chapter that feels like a reference to Angel's Egg - which I appreciated).
One of the things I really like about the PC Peter Grant graphic novels is that DC Guleed gets a lot more screen time in the graphic novels than she does in the books, and we get a bunch of wonderful little interludes with Nightingale.
The Hawk Moth has survived, Kunato is messing with things that he probably shouldn't be, and the exodus by the Lem most likely lead to everyone there getting killed.
