In October 2017 the hashtag "MeToo" went viral on social media and soon became a symbol of unity for women who had been sexually harassed or assaulted. This led to the launch of the #MeToo movement, a global campaign against sexual harassment--and in the process brought down hundreds of rich, powerful men. This book examines #MeToo's history, what the movement has accomplished, unexpected consequences, and where it is expected to go in the future.
