The characters in Crystal Kingdom are very well developed by this novel and each have their own quirks and quarks. I loved the romantic lead, Ridley Dresden. He is an interesting character, but not so interesting that he takes away attention from the plot and the main character, Bryn. Although there was moments I felt like the romantic relationship between Bryn and Ridley had slight room for improvement.
Crystal Kingdom was a great and intense read. I felt like this novel was the best in the series and wraps up the story extremely well. I found myself emotionally engaged in the story and riveted by what I was reading. I totally recommend Crystal Kingdom and give it the rating of FOUR AND A HALF STARS OUT OF FIVE!
