'With characteristic, clear-eyed style, Celia Roberts negotiates the shoals of biological and social reductionism to give us a rigorous, richly entangled account of contemporary puberty. She clarifies the anxieties around the 'precocious girl' and identifies the many tributaries that feed the moral panic around feminine sexual development. This book should be read by anybody interested in a critical account of girlhood, the life course, sexuality, and the ways the biological and the social collaborate in the history of the body.'
