A crisis has swept America. Hundreds of thousands have lost the ability to sleep. Enter the Slumber Corps, an organization that urges healthy dreamers to donate sleep to an insomniac. Under the wealthy and enigmatic Storch brothers the Corps’ reach has grown, with outposts in every major US city. Trish Edgewater, whose sister Dori was one of the first victims of the lethal insomnia, has spent the past seven years recruiting for the Corps. But Trish’s faith in the organization and in her own motives begins to falter when she is confronted by “Baby A,” the first universal sleep donor, and the mysterious “Donor Y.”
