Larry Ferrell died as he lived--changing the world. The legendary founder of the social network Headspace, which connects nearly everyone on the planet, Ferrell gave away his entire fortune on his deathbed--18 billion dollars, evenly divided between 140 randomly selected strangers. With the money came one simple condition: if any of the recipients dies, their shares are automatically redistributed to those still alive. The result? Kidnappings. "Accidents." Murder. Slowly but surely, the 140 are dwindling, and no one--not the rich and famous socialite, not the strangely prescient guru, not the tough-as-nails reporter--is safe. But death is not the end that it might seem. Behind this sinister experiment is a secret that Ferrell kept from everybody, including those responsible for the 140 program--and now all the masks are about to come off.
