This book was ultimately a big let down for me. So many questions that really should be answered, as its the final book of a trilogy, were just left open. Even the explanations that were given (like WICKED's whole reasoning for putting the kids through everything that they did) weren't enough and honestly didn't make a lot of sense to me. That being said, it was still an engaging read and you will not be bored reading this book. But if you're looking for more than constant action sequences and plot twists, you'll be disappointed too.
