Cameron desperately needs a new heart when he is offered the opportunity to take part in a radical and controversial experiment involving the transplant of a pig's heart. The writing is perfect, it paints the scenes so well without adding words that don’t need to be there. I hint at the was only because I first read her books, including the first three in this series when I was teenager (way way back) but I can't seem to get back into them as an adult.

Blackman portrays an engagingly vulnerable, multifaceted character in Tobey, who narrates the majority of the book, and through him creates for her readers profound moral and ethical dilemmas. I’m just struggling to see how we went from Noughts and Crosses to this book - they kind of feel like three very separate books connected loosely by the original world. So I think his death at the end of the last book was perfect, devastating but perfect for the character and clearly the end he was always running towards. The danger of being sucked into and destroyed by this violent world is brilliantly handled by Blackman .She also fears that he escaped the blast given that the person killed with Jasmine is finally identified as someone she has never heard of and she blames herself for killing an innocent man. Rival gangs are tearing up the neighbourhood and it's impossible to not ally yourself with one or the other. But when he's offered the chance to earn some extra money, how much could it hurt to just this once say 'yes'? I wasn't too sure whether I actually liked this book because up until 3/4 of the way through, the events were dramatic but you didn't necessarily need to read the book.

Instead, the story focuses on the two rival crime gangs which rule the area where the two young people live, and how they impact on their lives and on the community. It is very encouraging that Blackman's series of books has been so successful and is widely read and made available in UK schools – as it quite rightly should continue to be. However I don’t think it adds anything significant to the overall story as a result it feels quite removed from the original book in the series. I hear this book was an afterthought anyway and this series was originally going to be the first three books which is how I choose to view them having read this. I was mostly confused as to why I needed to read this as the ending for Checkmate left everything on good terms however, I now regret thinkin this and I am very glad that I have read it.

Little does he know what a chain reaction of violence and recrimination making those deliveries will cause. And when something happens to her, Tobey goes all out to get revenge and nullify the threats hanging over her and his family.
