In this is a bold and provocative book, Citron presents vivid accounts about online harassment. The stories she relates involve comments and behavior so vile and mean that her book could readily be an anthology of horror stories. But this book is a lot more than stories, for Citron examines why certain types of law are ill-suited to address the problem. She makes a powerful and creative argument for how civil rights law can be used to combat the problem, and her blueprint for a solution is practical and sound. Citron also thoughtfully examines the free speech implications of her approach. This is a great book and one that policymakers should pay attention to.
