The Rainbow by Yasunari Kawabata (author), Haydn Trowell (translator)

With the Second World War only a few years in the past, and Japan still reeling from its effects, two sisters - born to the same father but different mothers - struggle to make sense of the new world in which they are coming of age. Asako, the younger, has become obsessed with locating a third sibling, while also experiencing love for the first time. While Momoko, their father's first child - haunted by the loss of her kamikaze boyfriend and their final, disturbing days together - seeks comfort in a series of unhealthy romances. And both sisters find themselves unable to outrun the legacies of their late mothers.
