This book made me feel a lot of emotions. Strong emotion. So strong that I had physical reactions, like a fast beating heart, upset stomach, tears. I felt what Jack felt, and I actually felt sorry for him when he finally got out of the Room, and I didn't like reading about how hard it was for him. I wanted him getting out of the Room to be happy, but somehow it was sad. I didn't enjoy the second part of the book as much as the first. I would have rated this book five stars if it would have ended a few chapters after they escaped. Not a very uplifting book, but it gets four stars from me.
