I thought this was a really fun book, and a really good start to a series. I really enjoyed Leda's character and her chemistry with Nero. Even though this book was pretty short, the world seems well-developed and I liked that we were just kind of thrown into Leda's world, a dystopian version of the U.S. that had been nearly destroyed by a demon and angel civil war resulting in border towns walled off from a wasteland filled with monsters while angel overlords monitor the supernatural creatures existing in society. I do wish it was a little bit longer, and I'm excited to read the next book!
