Hunchback by Saou Ichikawa

Born with a congenital muscle disorder, Shaka Isawa has severe spine curvature and uses an electric wheelchair and ventilator. Within the limits of her care home, her life is lived online: she studies, she tweets indignantly, she posts outrageous stories on an erotica website. One day, a new male carer reveals he has read it all – the sex, the provocation, the dirt. Her response? An indecent proposal…

Written by the first disabled author to win Japan’s most prestigious literary award and acclaimed instantly as one of the most important Japanese novels of the twenty-first century, Hunchback is an extraordinary, thrilling glimpse into the desire and darkness of a woman placed at humanity’s edge.
