Two editions. Two narrators. One thrilling story. You can also choose to download Wil Wheaton's narration.

"I love working with Audible, in no small part because they’re committed to doing what’s right, both for my books, and the people who listen to those books. There's a really excellent reason for Lock In to have two entirely different versions, so when it came time to make the audiobook, Audible did an ingenious thing: they asked both Wil Wheaton and Amber Benson to record entire versions of the book. As the author, I’m impressed with Audible’s commitment to my narrative - and I’m geeking out that both Wil and Amber are reading my book. This is fantastic." (John Scalzi)

A blazingly inventive near-future thriller from the best-selling, Hugo Award-winning John Scalzi.

Not too long from today, a new, highly contagious virus makes its way across the globe. Most who get sick experience nothing worse than flu, fever, and headaches. But for the unlucky one percent - and nearly five million souls in the United States alone - the disease causes "Lock In": Victims fully awake and aware, but unable to move or respond to stimulus. The disease affects young, old, rich, poor, people of every color and creed. The world changes to meet the challenge.

A quarter of a century later, in a world shaped by what's now known as "Haden's syndrome", rookie FBI agent Chris Shane is paired with veteran agent Leslie Vann. The two of them are assigned what appears to be a Haden-related murder at the Watergate Hotel, with a suspect who is an "integrator" - someone who can let the locked in borrow their bodies for a time. If the Integrator was carrying a Haden client, then naming the suspect for the murder becomes that much more complicated.

But "complicated" doesn't begin to describe it. As Shane and Vann began to unravel the threads of the murder, it becomes clear that the real mystery - and the real crime - is bigger than anyone could have imagined.

BONUS AUDIO: Audible's audio edition of Lock In contains the bonus novella, Unlocked: An Oral History of Haden's Syndrome, written by John Scalzi and narrated by a full cast.

"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)

John Scalzi returns with Head On, the stand-alone follow-up to the New York Times best-selling and critically acclaimed Lock In. Chilling near-future SF with the thrills of a gritty cop procedural, Head On brings Scalzi's trademark snappy dialogue and technological speculation to the future world of sports.

Hilketa is a frenetic and violent pastime where players attack each other with swords and hammers. The main goal of the game: obtain your opponent's head and carry it through the goalposts. With flesh and bone bodies, a sport like this would be impossible. But all the players are "threeps", robot-like bodies controlled by people with Haden's Syndrome, so anything goes. No one gets hurt, but the brutality is real, and the crowds love it.

Until a star athlete drops dead on the playing field.

Is it an accident or murder? FBI agents and Haden-related crime investigators Chris Shane and Leslie Vann are called in to uncover the truth - and in doing so travel to the darker side of the fast-growing sport of Hilketa, where fortunes are made or lost and where players and owners do whatever it takes to win, on and off the field.
