I read Noughts and Crosses quite a few years ago when I had bought it for my teenage granddaughter and was checking it out. I loved it and had high hopes for this one.
Most of the way through it delivered but then as the story grew to a close it was slightly disappointing causing me to give three stars when I might have given four.

A fairly fast moving story about the Noughts and Crosses lives.
I think it would have been important to have read previous books and I had to make assumptions about the community reversal of black versus white in this book.

It is an interesting theme which works well in the story and I can see that it appeals to the YA market.
It is certainly worth recommending to those who have read the previous books, they will be keen to read on. However, the end of the book does not end the story which I always find disappointing.
