A major step up from the first book, adding layers and scope to this world with a delicious mystery. A couple of let-downs: the unusual way some scenes were edited made for lack of clarity (early on, Sylah moves locations without a clear signal and was suddenly inside when she was outside) and my least favourite tropes of a character not revealing important information until it's plot relevant. But! Loved the new perspectives, the tighter focus, and awesome world. Stoked for the final book!
