Crystal Keepers by Brandon Mull

4.0

My least favorite book in the series so far, and I think it will be my least favorite upon finishing the series. I just did not like the kingdom of zeropolis. It didn't fit with the vibe of the setup of the five kingdoms. Having the technology and American elements just ruined it for me. I did enjoy the surprises in the book but I'm glad to be moving on to book 4.
