I adored All the Birds in the Sky, and I was initially intrigued by this book, especially the world-building on a tidally-locked planet. But this book lost me pretty quickly. The main characters feel emotionless and dislikable, the secondary characters are barely even there, the plot moves way too slowly and there's too many events in the plot that just...happen... semi-randomly. I was also extremely surprised to find out that this is a stand-alone book, because it ends so suddenly I assumed it had to be continued in a second book. This is a Stephensonian level of abrupt unresolved ending. Really, really disappointed.
