The story of a young woman's relationship with her brother, the long shadow cast by his childhood brain tumour, and her harrowing sexual awakening. Not so much a stream-of-consciousness, as an unconscious railing against a life that makes little sense, and a shocking and intimate insight into the thoughts, feelings and chaotic sexuality of a vulnerable and isolated protagonist, this novel plunges inside its narrator's head. This isn't always comfortable - but it is always a revelation.
