Even the oldest and most technologically advanced of the galaxy’s sentient races, the Raiel, do not know its origin, its makers, or its purpose.But then Inigo, an astrophysicist studying the Void, begins dreaming of human beings who live within it. Inigo’s dreams reveal a world in which thoughts become actions and dreams become reality. Inside the Void, Inigo sees paradise.
