This is the third in the series and based on the flow I imagine there will not be any additional ones. That being said, as with the others I thoroughly enjoyed this story. I started out listening to this one as an audible while doing chores and because it would sync with my e-reader I finished it on my kindle and I enjoyed both formats.
The narrator of the audible did a credible job switching between characters (she was also the narrator of the prior 2 in the series) and in some ways made them come to life in a manner that I am not sure I would have captured had I just been reading the story. Along those lines I was so captivated by the story that when I finished my chores for the day, I had to pick up my e-reader to finish the book because I just could not put it down.
