Dahlia black

Summary/Review: "Discovered by Dr. Dahlia Black, the mysterious Pulse was sent by a highly intelligent intergalactic species that called themselves the Ascendants. It soon becomes clear this alien race isn’t just interested in communication—they are capable of rewriting human DNA, in an astonishing process they call the Elevation. Five years after the Pulse, acclaimed journalist Keith Thomas sets out to make sense of the event that altered the world. Thomas travels across the country to interview members of the task force who grappled to decode the Pulse and later disseminated its exact nature to worried citizens. He interviews the astronomers who initially doubted Black’s discovery of the Pulse—an error that critics say led to the world’s quick demise. Thomas also hears from witnesses of the Elevation and people whose loved ones vanished in the Finality, an event that, to this day, continues to puzzle Pulse researchers, even though theories abound about the Ascendants’ motivation." --Amazon.com.
