Cathy Hopkins has sold millions of books, most of them written for teenage girls. After reading her latest book, Zodiac Girls: Recipe for Rebellion, I credit her popularity with a tone that both accurately captures the anxieties of adolescent life, and also achieves a likeability of character that is the key to most of today’s popular literature. Formerly an art school student, rock singer, aromatherapist and teacher of meditation techniques, Hopkins has an edge to her, a wit and style only found in people who have lived life outside of the lines to a certain degree.
