I liked this book, but in a lot of ways it felt so different from the rest of the series that they hardly mesh in my head. It feels kind of like a spinoff, but still with the same main characters. Felix and Mildmay go to a very different place, where everyone does very different things, and they themselves change so much so as almost to become unrecognizable.... Felix mostly. I've been wanting more character growth from Felix for the entire series, but coming as it did in this (very different) final volume, it sometimes felt like it wasn't really even Felix at all.All that being said, I enjoyed it immensely. And I feel somewhat satisfied with the end of the series, though I could go on happily reading more about Felix and Mildmay for quite some time.
