The year is 2322. Humanity has expanded into the stars, inhabiting over 100 worlds across a third of the galaxy. Though thriving as never before, they have discovered neither alien life nor the key to utopia. Earth struggles to retain authority over far-flung planets and free-wheeling corporations while an uneasy armistice with a breakaway federation hangs by a thread as the former rebels rise in wealth and power.

The year is 2322 and humanity is under attack. An engineered war between rival superpowers escalates even as the shadowy Metigen armada begins attacking colonies on the frontiers of settled space.

What does it mean to be human? What if the price of saving humanity is giving up your own?

To achieve their extraordinary triumph over the invading Metigen armada, humanity put aside its myriad of political and social conflicts and united against a common foe intent on annihilating civilization. In victory, unparalleled peace and prosperity are theirs for the taking - if they can keep hold of them.

The technology behind Project Noetica is on the loose. Prevos - individuals and AIs sharing a single body - are spreading across the galaxy. Now two opposing but inexorably related forces, the Order of the True Sentients and the Zelones cartel, led by Olivia Montegreu, threaten to plunge the galaxy into chaos. OTS believes Prevos are monsters who endanger humanity, and it intends to destroy them by any means necessary.

Alex Solovy and Caleb Marano risked everything to learn the hidden purpose behind the Metigen's multiverse portal network, but nothing could have prepared them for the answer. Humans are a genetic recreation of the Anaden, the dictators and overlords of the master universe. Aurora is a recreation of their origins, created by the Metigens in a desperate gambit to understand the nature of their enemy, and so find a way to defeat them. Instead it may turn out that history always repeats itself.

For millennia the Anadens have ruled the known universe. They believe they've crafted the perfect empire, ordered and impervious to challenge. They believe the fight has been crushed out of the species they subjugate. They are wrong. It's a suicide mission, without a doubt. Alex Solovy and Caleb Marano must steal crucial intelligence from the Anadens' central military headquarters. To succeed, they'll need to navigate a strange universe ruled by a cabal of powerful immortals.

The Anaden Directorate has ruled Amaranthe for millennia, subjugating species and galaxies in a never-ending quest for control and order. For as many millennia, the anarchs have rebelled, defiantly claiming their own freedom - yet without hope of winning it for everyone. Now, an alliance with humans offers a tantalizing chance to at last defeat their immortal masters. But can they trust an ally who looks suspiciously like the enemy?

What began as a chance discovery of an anomalous signal is now a multiverse war between humanity and its genetic ancestors over who controls the levers of life and death. Over who decides what life is and whether it will be allowed to exist. For the ruling Anaden Directorate, victory means immortality. For humanity, defeat means extinction. On the heels of a breakthrough in wormhole technology, AEGIS and the anarchs enjoy the upper hand in the war. But their escalation pushes the Directorate to the brink, and now it will stop at nothing to destroy its enemy.

The Earth Alliance rules 82 worlds, controlling an empire that spans a third of the Milky Way. But when its leaders stray too far from the democratic principles on which it was founded, one colony - one group of daring rebels - will risk everything in order to reclaim their freedom. Before Alex Solovy was a successful interstellar scout, she was building starships and planning for the day when she would fly one she called her own.

The Asterion Dominion is at peace with its neighbors and itself. Its citizens enjoy great freedoms and all the luxuries their biosynthetic minds can imagine, design, and create. But beneath the idyllic veneer, something is going wrong. People are going wrong, driven to commit inexplicable crimes without motive or purpose. And once imprisoned for those crimes, they simply vanish. Psyche-wiped and dumped in an alley five years ago, awakened into a culture where ancestral memories stretch back for millennia, Nika Tescarav's past is a blank canvas. But if whoever erased her did so in the hope of silencing her, they should have tried harder.

Seven hundred thousand years ago, the Asterions fled persecution for their pro-synthetic beliefs. In the safe harbor of a distant galaxy, they have evolved into a true biosynthetic race and built a thriving society upon the pillars of personal autonomy, mutual respect, and boundless innovation. Now that society is fracturing at the seams. Beneath lies built upon lies, the shocking truth as to why threatens the future of not merely the Asterions, but all life in the universe.

The Asterion Dominion government has fallen, its rulers slain - but in the Dominion, the dead rarely stay that way. A doomsday clock rushes headlong toward the day the monstrous alien shape-shifters known as the Rasu will demand their next tribute of lives. When denied it, the Rasu will burn every Dominion world to the ground. Unless they can be stopped. Nika, Dashiel, and their allies fight to hold onto the reigns of power even as they search for a way to defeat the enemy.

Fourteen years after the Displacement flung humanity into a universe teeming with alien life, a tenuous alliance has taken root among humans, Anadens, and numerous other species. The wounds of war and revolution have begun to heal, peace and prosperity are within reach, and the architects of the Displacement - Alex Solovy and Caleb Marano - are enjoying an idyllic existence on the living planet of Akeso.

Concord, with its vaunted indestructible warships and dimension-bending weapons, has been knocked back on its heels. A stunning loss in the Battle of Namino has left its best and brightest leaders scattered, trapped, or thought lost. The Rasu press their advantage, laying siege to Namino and cutting it off from the rest of civilization. For Miriam Solovy, a coup attempt by Anaden rebels and a flaring conflict with the militaristic Savrakaths are the least of her concerns.
