I am really really glad that I only started reading this series last week because I had the satisfaction of devouring the whole thing. Elisa remains an incredibly wonderful viewpoint character and her journey as she discovers herself remains one of the best I have read recently. Carson's sense both for what the rules of the genre are and where to judiciously break them remains excellent.
My biggest disappointment was with the bits that were not in Elisa's voice. They just seemed a bit less real and the voice seemed more generic...and the perspective didn't seem to add much to the story. Still, it was a satisfying conclusion to a great series.
