I think this is a useful book, and the author is well qualified to write it. She has an excellent combination of experience in the field, work as an educational psychologist, and academic doctoral research on the topic. Her earlier 1989 book was a seminal contribution to the area of school bullying. This book adds to a relatively small literature on the nature of girls bullying, which is known to be different from that of boys. There is thorough coverage of other relevant academic literature, as well as interesting insights from the author's own work. It should appeal to both professional and academic audiences.
