This was a good ending to the series. There was one thing I would have liked cleared up that wasn't, but it could make for a good short story. Oddly enough, this is the only YA book, or book in general even, where a main character is in a gay relationship. It's a change of pace and does add diversity to the characters, which is nice. This series could be expanded further beyond this trilogy and I would read it. Especially if it came form a different kingdom within the red london world. Lots to build on and very interesting.
