This book has a totally different feel to the original Night Angel trilogy. It both works and throws me of it some times. The book starts fairly shortly after Beyond the Shadows and it one of it's main focuses is how the events from the end of the primary saga has changed the characters and the world. We get a fair bit of world building as we visit new places in the world and there are interesting character developments as well for the main characters of the book. If you like the original series then this is worth a read. You should be fine with having this as your first book into Midcyru since this is the first book in a new series, however you'll probably miss out on quite a few details.
