AD 3580. The Intersolar Commonwealth has spread through the galaxy to over a thousand star systems. It is a culture of rich diversity with a place for everyone. A powerful navy protects it from any hostile species that may lurk among the stars. For Commonwealth citizens, even death has been overcome.
At the center of the galaxy is the Void, a strange, artificial universe created by aliens billions of years ago, shrouded by an event horizon more deadly than any natural black hole. In order to function, it is gradually consuming the mass of the galaxy. Watched over by its ancient enemies, the Raiel, the Void's expansion is barely contained.

Inigo dreams of the sweet life within the Void and shares his visions with billions of avid believers. When he mysteriously disappears, Inigo's followers decide to embark on a pilgrimage into the Void to live the life of their messiah's dreams - a pilgrimage that the Raiel claim will trigger a catastrophic expansion of the Void.

Aaron is a man whose only memory is his own name. He doesn't know who he used to be or what he is. All he does know is that his job is to find the missing messiah and stop the pilgrimage. He's not sure how to do that, but whoever he works for has provided some pretty formidable weaponry that ought to help.

Meanwhile, inside the Void, a youth called Edeard is coming to terms with his unusually strong telepathic powers. A junior constable in Makkathran, he starts to challenge the corruption and decay that have poisoned the city. He is determined that his fellow citizens should know hope again. What Edeard doesn't realize is just how far his message of hope is reaching.

Long ago, a human astrophysicist, Inigo, began dreaming scenes from the life of a remarkable human being named Edeard, who lived within the Void, a self-contained microuniverse at the heart of the galaxy.
There, under the beneficent gaze of mysterious godlike entities, humans possessed uncanny psychic abilities, and Edeard's were the strongest of all. Equally strong was his determination to bring justice and freedom to a world terrorized by criminal violence and corruption.

Inigo's inspirational dreams, shared by hundreds of millions throughout the galaxy-spanning gaiafield, gave birth to a religion - Living Dream. But when the appearance of a Second Dreamer seemed to trigger the expansion of the Void - an expansion that is devouring everything in its path -the Intersolar Commonwealth was thrown into turmoil. With the adherents of Living Dream determined to set forth on a dangerous pilgrimage into the Void, interstellar war threatens to erupt.

With time running out, the fate of humanity hinges on a handful of people. There is Araminta, only now awakening to the unwelcome fact that she is the mysterious Second Dreamer - and to the dire responsibilities that go with it; Inigo, whose private dreams hint at a darker truth behind Edeard's legendary life; Paula Myo, the ruthless field operative of the Commonwealth, whose search for Araminta and Inigo is about to yield a most unpleasant surprise; and Justine, whose desperate gamble places her within the Void, where the godlike Skylords hold the power to save the universe...or destroy it.

From audible.com:

An innovator praised as one of the inventors of "the new space opera", Peter F. Hamilton has also been hailed as the heir of such golden-age giants as Heinlein and Asimov. His star-spanning sagas are distinguished by deft plotting, engaging characters, provocative explorations of science and society, and soaring imaginative reach. Now, in one of the most eagerly anticipated offerings of the year, Hamilton brings his acclaimed Void trilogy to a stunning close.

Exposed as the Second Dreamer, Araminta has become the target of a galaxywide search by government agent Paula Myo and the psychopath known as the Cat, along with others equally determined to prevent - or facilitate - the pilgrimage of the Living Dream cult into the heart of the Void. An indestructible microuniverse, the Void may contain paradise, as the cultists believe, but it is also a deadly threat. For the miraculous reality that exists inside its boundaries demands energy - energy drawn from everything outside those boundaries: from planets, stars, galaxies...from everything that lives.

Meanwhile, the parallel story of Edeard, the Waterwalker, as told through a series of addictive dreams communicated to the gaiasphere via Inigo, the First Dreamer, continues to unfold. But now the inspirational tale of this idealistic young man takes a darker and more troubling turn as he finds himself faced with powerful new enemies - and temptations more powerful still.

With time running out, a repentant Inigo must decide whether to release Edeard's final dream: a dream whose message is scarcely less dangerous than the pilgrimage promises to be. And Araminta must choose whether to run from her unwanted responsibilities or face them down, with no guarantee of success or survival. But all these choices may be for naught if the monomaniacal Ilanthe, leader of the breakaway Accelerator Faction, is able to enter the Void. For it is not paradise she seeks there, but dominion.
