Selected on the list for World Book Night 2013, I picked up the e-edition, complete with alternative ending, which Blackman wrote for the occasion. The story centres on teenagers Callum and Sephie, growing up in a society split along racial faultlines and the experiences of their respective families. It is a romantic/tragic tale of young love stifled by societal tensions, which the author explores sensitively. The first in a series of novels, the plotline was developed well and with pace. A very enjoyable read.
