Book excerpt: Longlisted for the Orange Prize for Fiction A Radio 4 Book at Bedtime Two sisters grow together and apart into their emerging selves. Frankie pulses with curiosity and risk; Kate is watchful, all eyes and ears. Immersed in the heat and colours of Hong Kong in the 1960s, theirs is a world of fishermen and insurgents, temple gods and ghosts, of blinding light and dark, dark waters. As Frankie's behaviour becomes more and more outrageous in her defiant attempt to win her parents' attention, Kate retreats into a quiet desperation, unable to act to save the soul for whom she would sacrifice everything - Frankie.
