 This book was just about 85 percent awesome. The heroine is a British version of Jael from John Skovron's Misfit, absent dad, dead mother, supernatural organization and all, combined with a bit of Alina Starkov and Katniss. She's a member of a Shadowhunter-like organization of dwindling numbers that's called to battle over a mortal-instrument-like object with weird supernatural powers. I loved the pretty much stereotype-free religious and racial diversity and that it doesn't hate on Christianity the way a lot of other books do and this could have. Unfortunately, I was confused by the moral order of the angels and the last few action chapters had a lot of the bad traits of Ruin and Rising and Clockwork Princess, which disappointed me. They're worth reading, however, for the rest of the book. 
 It has a sequel set it Russia. 
 Don't screw up, please. I've had enough Etanoviches to last the rest of my life.
