In the spring of 2014, an American rap star unwittingly triggered an online hurricane with the ease of a tweet. Hitting an unprecedented nerve on Twitter, accompanied with the hashtag #BringBackOurGirls, the message called for the release of 276 Nigerian schoolgirls who'd been kidnapped by a little-known Islamic terrorist sect called Boko Haram. Bounty hunters, the manpower of western militaries and special Swiss agents were all deployed but they either met road block after road block or flew home empty-handed. Twitter flitted to the next crisis, leaving the Chibok girls to take survival into their own hands. A heart-stopping thriller, a riveting narrative history and an incisive cultural analysis, this title is the definitive account of a kidnapping and digital campaign that changed our understanding of warfare, terrorism and online activism.
