After reading the book 3 times I feel I have actually gone on Bruno's journey through his life at every moment. When he realises things or gets them wrong you feel like you would have made those decisions too and how oblivious you were at that age even when it was going on around you.
This book is fantastic and definitely worth reading. I would recommend this to anyone over the age of 11. But I would also recommend reading before you watch the film which is also good but to really feel the book and get the story you must read it and make your own view of it.
I chose this book for my common entrance relationships piece and it is really working well for me.
