Its a good read. The concept of death and memories is very interesting. But some where I felt that there were a lot of loop holes that were left unanswered. I was also very confused if the character was a girl or a boy until somebody calls "her". There's also no physical description of her so I had to make up my own version of Mac. I was expecting something a little more deeper from the book but as it's classified as YA I guess it's expected. would have loved to read a more adult version of the book.
