This book is so cool. I finished it in about a week because it is so good I could not put it down. It has a cool twist that you did not see coming. It is about a girl named Kirsten and a boy at school named Walk (really Walker) and their lives. I read it for a summer reading project. Probably the best project you could ever do. SO TAKE YOUR EYES OFF THE T.V. AND READ IF A TREE FALLS AT LUNCH PERIOD.
