When I first started the book I had a hard time with the different point of views between Sarah and Miles. I think that was only because I was just getting to know the characters though, and once I got to know them better, I enjoyed the two POV's very much.
Miles, Sarah, and their parents have escaped the suburbs to live in a tiny shack out in the middle of nowhere after a massive volcano causes a huge disruption in everyone's lives. The family has gone "off the grid" so to speak and it just trying to survive completely on their own. Mile thrives off this, however Sarah does not. Sarah longs for school, friends, the mall, and modern necessities such as hot water. I enjoyed the different feelings of all the characters on this issue and thought it gave the story more depth. It was nice to read a book where all the characters were going through the same tragedy, however they all felt differently about it.
When Sarah starts school, things change a bit. She meets a few new "friends" who turn out to be not her friends at all. However, she meets Ray though, she meets a true friend and I really adored their relationship. Ray didn't care if Sarah was rich, or off the grid, or where she came from like the other people at school do. He just wanted to be her friend. I really enjoyed his character and think he is a great role model for young teenage boys. It's not easy to find a teenager (let alone a boy) who doesn't judge you. I really liked reading about their relationship growth and struggles.
Overall, this book was ok. It didn't leave with me a desire to read "Memory Boy", but I did enjoy this book and think it's a great book about family values and the importance of sticking together through thick and thin.
