This book has a wildly interesting setting, but the plot didn't fully live up to my expectations. I would love to read more about the worlds and their magics and how they're bound together and distinct, more about their history, and even more about these characters. Kell and Lila were interesting but I craved a greater depth to their stories and their motivations. I want to read the next book from this series because I feel like this was such a small story compared to what is possible from its building blocks.
