First off all, this is a really short and easy read, i finished it in one night, but do not let the length of the book put you off!
The story centres around Jonas, who is about to become a 12 and start his training into adulthood. Jonas appears to have been brought up in a perfect home, with the perfect family, within a perfect community. Everyone knows the rules and what is expected of each other. When Jonas starts his training he begins to realise the truth.
The book itself raises a lot of questions, especially regarding euthanasia and what if this happened...what if that happened?
