Although written primarilly for young teens there is much, in this book, that adults can enjoy. In fact I would advise parents to read this book as a good example of what their children should be reading.
This book satisfies on many levels. On the one hand it is a very good story - fast paced and exiting. The characters have real depth and you end up caring about what happens to them.
On the other hand the book highlights serious issues such as the way our education system is going, loneliness, relationships and how different people cope in a crisis.
As one reviewer pointed out 'this book makes you think'. Something a lot of books, these days, fail to do.
An enjoyable and challenging read.
