The Ace of Skulls

This was an absolutely perfect sendoff to the series. The stakes get raised even higher than they had in previous books, all the loose plotlines get tied up, and Frey and his crew get to be Big Damn Heroes one last time. I was sold on this series when it was originally described to me (as “Steampunk Firefly with airships”), but it managed to grow beyond any simple comparison or elevator pitch into a wonderful tale, and a wonderful crew of characters.
