Bestselling, award-winning futurist David Brin returns to globe-spanning, high concept Science Fiction with Existence.

Gerald Livingston is an orbital garbage collector. Only now, high over the blue Earth, he spots something that’s … unusual… and pulls it in, sending rumors across Earth's infomesh about an "alien artifact." Amid a maelstrom of worldwide speculation, the Artifact is a game-changer. A message in a bottle? An alien capsule that wants to communicate… or deliver a warning? After surviving countless pitfalls – natural disasters, nuclear terrorism, rising seas – might this push our troubled era over the brink of chaos? The world reacts as humans always do: with fear and hope and selfishness and love and violence. And insatiable curiosity.

Brilliant and gripping, David Brin’s novel of the near future is the work of a modern master of science fiction.
