Eimear McBride's debut tells, with astonishing insight and in brutal detail, the story of a young woman's relationship with her brother, and the long shadow cast by his childhood brain tumour.

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.

To read A Girl Is a Half-formed Thing is to plunge inside its narrator's head, experiencing her world first-hand. This isn't always comfortable - but it is always a revelation.

Touching on everything from family violence to sexuality and the personal struggle to remain intact in times of intense trauma, McBride writes with singular intensity, acute sensitivity, and mordant wit. A Girl is a Half-formed Thing is moving, funny – and alarming. It is a book you will never forget.
