I LOVED this book!! It was so amazingly original. With the hundreds of books out there taking the same concept and just altering it (ex: vampires or the like) a new concept was so refreashing.
I also loved the people in it. They were so relatable. They felt things that I could imagine feeling in that situation. It made me contemplate for hours about what I would do if I were in their shoes. If I were in that situation, who would I see in the mask?
I thought about this book well after reading it, which is a sign of something very well written :-)
