I would definitely classify this as one of the more stressful books in the Kingdom Keepers realm. I loved getting more of a background on the Fairlies and how we got each of their POVs. Though I missed the full ensemble of characters that you get in the main series books, I did find myself pleased to be spending more time with Amanda, Jess, and Mattie. And even the parents and Joe. Wouldn't call it my favorite book, but it's a great addition to the universe and it made me extremely excited to start The Return series to see what ends up happing with the Kingdom Keepers.
