Publisher's Synopsis
Discover the history of Haden's Syndrome, the virus that created the world of John Scalzi's inventive near-future thrillers Lock In and Head On, in the prequel novella Unlocked.
Not long from now, a virus will sweep the globe. Most will suffer no worse than flu-like symptoms, but an unlucky one percent will be changed forever. Hundreds of millions become "locked in", awake, aware, but completely unable to control their bodies.
