If you live in the UK I've found a great offer which might interest you! In Tesco I picked up the first two in the noughts and crosses sequence by Malorie Blackman for a total of £3.89. Love it! Tesco's books are always good value for money but their book packs are amazing!
I'm not going to give you the blurb for knife edge as it is the second in the series but here is the blurb for noughts and crosses:
Two young people are forced to make a stand in this thought-provoking look at racism and prejudice in an alternate society.
Sephy is a Cross -- a member of the dark-skinned ruling class. Callum is a Nought -- a “colourless” member of the underclass who were once slaves to the Crosses. The two have been friends since early childhood, but that’s as far as it can go. In their world, Noughts and Crosses simply don’t mix. Against a background of prejudice and distrust, intensely highlighted by violent terrorist activity, a romance builds between Sephy and Callum -- a romance that is to lead both of them into terrible danger. Can they possibly find a way to be together?
In this gripping, stimulating and totally absorbing novel, black and white are right and wrong.
Till next time, happy reading!
