Sephy is a Cross, one of the privileged in a society where the ruling Crosses treat the pale-skinned noughts as inferiors. But her baby daughter has a nought father – Callum. Eaten up with bitterness, Callum’s brother Jude, blames Sephy for the terrible losses his family has suffered. Now Jude’s life rests on a knife edge. Will Sephy be forced, once again, to take sides?
i like this book and i buyed it with audio CD too, maybe you can too
As Jacqui, I’m from Chile too, and I need to read knife edge in spanish because I loved the first book.. Anyone knows if the book has been translated?
Hi, I’m from Chile. I read Noughts & Crosses and I loved the story. Now I want to read “Knife Edge”, but I don’t find this book in Spanish 
did callum mean what he said in the letter
This is definitely my favourite series of books. It’s so amazing, and truly touched me like no other book has. Seriously fantastic.
ps; I always get emotional thinking about Callum. He’s my favourite and always will be.
Queria saber si Los libros ya estan traducidos en español… especialmente Knife Edge… lei el Primer Libro… Blanco y Negro… Me encanto… me gustaria terminar de leer toda la historia
The noughts and crosses series is truly powerful. I read this book in about a day because it really is a page turner. Sad and full of emotion x
I love this bookk because you start to see a little bit about how Jude is hurting and I sort of feel sorry for him because he will not let himself love I still read the books like 24/7 xx
i absolutely LOVE the Noughts and Crosses series! They are the best books I have ever read! Truly amazing, I couldn’t put any of them down! <3
They are all very powerful books that touch a very sad subject.Ithink that what callum said in the letter to Sephy was quite emotional, and quite mean. They spent all that time together and now Callum says he did not mean any of it.

I think all four of the noughts and crosses series are very touching and moving. They make people stop and think racism is rong.I think all of the series are amazing,but at the same time make you stop and think.Just think.
malorie, this is my favorite book ever, this series has been un-put-down-able, you recently came to my school and well, i thought the books where brilliant, i have read noughts and crosses and knifes edge in 6 days, i cant wait to read checkmate. you have inspired me !!! i though what you did to stephy with callums note really shook up her life and well, i think stephy is a bit mean to meggie, i though no other book would be better than noughts and crosses but i thought wrong, kife edge is amazing

I love the Noughts and Crosses series! So far I am up to Knife Edge. When I read what Callum wrote in that letter to Sephy, I thought he sent her that so Sephy would think that she could go off with some other man, not stay with Callum, who is now dead.
This is my favourite book of the four of them. Read it years ago and now I’m a young adult I appreciate them more after a quick re-read. Jude is my favourite character because of his lack of feeling and especially his denial. Cara’s character really got to me, she was so nice, but I guess it had to be done. Absolutely fab book which strangely makes me sadder than reading the 1st one Soooo powerful. It’s about time there was some decent books depicting the shoe on the other foot – I recommend them to everyone!!!
how many books are they i have got them from my school libary and ive read noughts and crossers and now im on knife edge then checkmate but i thought there was only 3 not 4 :/ xx
