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.
Praise for Lock In
"This is the kind of thriller that Michael Crichton, Lincoln Child, and James Rollins do so well. Add John Scalzi to that list." --Douglas Preston, #1 NYT bestselling author of The Kraken Project and Impact "As much as Scalzi has the scientific creativity of a Michael Crichton, he also has the procedural chops of a Stephen J. Canell to craft a whodunit with buddy-cop charm and suspects aplenty--most of them in someone else's body." --USA Today
