Weaker than the other two by necessity, this could not be much of a puzzle book as it had to draw the story to a close. I found the ending a bit unsatisfying, even as I appreciated the continuation of moral gray areas. There was one particular part about Cia's candidacy that I found extremely gratifying, especially with the tendency of the character to go all mary sue during the telling of this story. 
 In the end? It was a good YA series that didn't challenge itself too much. It was never really sure of its world building, yet delivered a lot of reading excitement despite that.
