In her groundbreaking book, Now I Know Who My Comrades Are: Voices from the Internet Underground, Emily Parker, formerly a State Department policy advisor, writer at The Wall Street Journal and editor at The New York Times, provides on-the-ground accounts of how the Internet is transforming lives in China, Cuba, and Russia. This book introduces us to an army of bloggers and tweeters—generals and foot soldiers alike. These activists write in code to outsmart censors and launch online campaigns to get their friends out of jail. They refuse to be intimidated by surveillance cameras or citizen informers. Even as they navigate the risks of authoritarian life, they feel free. Now I Know Who My Comrades Are is their story.
