Continuum

2020

Humanity has seized its destiny among the stars. But space remains vast and untamed, and nothing has prepared us to face the dangers rising from the deep shadows of the void. 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. But growing troubles fester beneath the surface of this alliance. An upstart species offers allegiance with one hand but readies weapons of mass destruction with the other, while the Anadens, leaderless and adrift for years, increasingly refuse to play by humanity’s rules. As tensions simmer, Nika Kirumase, leader of the Asterions—a splinter group of former Anadens thought aeons dead—arrives bearing a warning of a terrifying enemy advancing across the void. Known as the Rasu, the powerful race of shapeshifting metal has already killed tens of thousands of Asterions in its quest to control all of known space. Nika’s people have struck a blow against the Rasu, and now they race against time to prepare for the coming reprisal. An alliance with humanity stands to give them a fighting chance against their enemy. But for humanity, such an alliance may cost them everything, pushing the fragile peace they fought so hard to achieve to the breaking point and beyond. \* In Amaranthe, where exotic alien life, AIs, wormholes, indestructible starships and the promise of immortality rule the day, no feat seems out of reach for humanity. But when the worlds of Aurora Rhapsody and Asterion Noir collide and the Rasu horde descends upon them both, more will be asked of heroes past and future. More will be given and more taken, and when the dust settles the very fabric of Amaranthe will be changed forever.

2020

Nothing has prepared humanity for an enemy on the scale of the Rasu. Now, after a devastating defeat no one saw coming, the dream of victory has become a battle for survival. 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. After blowing up the Concord flagship to prevent its capture by the Rasu, she is awakened in a new body and expected to don the mantle of leadership once again. But how can she lead Concord in the fight against the Rasu when humanity doesn’t trust regenesis and she no longer trusts herself? For Caleb Marano, nothing matters more than family. When his niece is trapped behind enemy lines, he turns his back on the peaceful sentient planet he shares a consciousness with in order to rescue her. If he hopes to succeed, he must become the killer he once was, even if it costs him everything. For Alex Solovy and Nika Kirumase, however, the crucible of two deadly intergalactic conflicts has taught them that survival is not enough. Together they will cross every line and break every rule to accomplish the impossible, end the siege of Namino and take the fight directly to the enemy. \* In Amaranthe, where exotic alien life, AIs, wormholes, indestructible starships and the promise of immortality rule the day, no feat seems out of reach for humanity. But when the worlds of Aurora Rhapsody and Asterion Noir collide and the Rasu horde descends upon them both, more will be asked of heroes past and future. More will be given and more taken, and when the dust settles the very fabric of Amaranthe will be changed forever.

“Everything we have done from the start of this endeavor has been risky. Is the goal not worth any risk?” In the aftermath of Namino’s liberation, everyone seeks a moment of peace to catch their breath and regroup. But the Rasu will not be waylaid for long, and peace soon becomes a race against time before the next onslaught. Alex and Caleb search distant stars and the ruins of a dead civilization for a secret weapon that may hold the key to defeating an enemy who cannot be killed by conventional means. In the Dominion, Nika and Dashiel probe the mysteries of kyoseil in search of answers, but the Asterions’ bond with this ancient and enigmatic life proves more complicated than they ever realized. “You act as if there are no consequences for your actions and no price for your foolish decisions. It is time to remind you that there is always a price to be paid.” Formidable as they are, the Rasu are not the only foe seeking to destroy Concord. The Savrakaths have seen their cities leveled and fleets decimated by rebel Anaden forces. Now they marshal their last resources for a final vengeance-fueled strike—against the wrong enemy. After a failed coup attempt, the Anaden leadership bickers and squabbles amongst themselves—until a ghost from the past returns, determined to finally unite his people. But those who have wielded unbridled power for millennia will not give it up so easily. Yet amid the deadly battles and insurrections, struggles of faith, hope, friendship and love light the way forward, because winning is about more than just surviving. \* In Amaranthe, where exotic alien life, AIs, wormholes, indestructible starships and the promise of immortality rule the day, no feat seems out of reach for humanity. But when the worlds of Aurora Rhapsody and Asterion Noir collide and the Rasu horde descends upon them both, more will be asked of heroes past and future.

All Our Tomorrows

2021

War has come to Concord. Now no one and nowhere is safe. When indestructible warships and dimension-tearing weapons are not enough to defeat the enemy, how do you protect thousands of worlds and trillions of citizens from a Rasu tidal wave bent on devouring everything in its path? The Rift Bubbles offer much-sought protection, but is the safety they promise anything more than an illusion? A weapon crafted by the nearly extinct Ourankeli may hold the key to gaining the upper hand—or it may be a doomsday bomb too dangerous to chance wielding. The Asterions strive tirelessly to improve upon and create new weapons that can kill Rasu, even as Nika Kirumase draws tantalizingly close to unlocking the true power of kyoseil. Yet for every strategic move Commandant Miriam Solovy makes to thwart the Rasu’s advances, the enemy swiftly counters in a deadly battle of escalation. We don’t need to fear death, for it cannot hold us. Regenesis, long the exclusive domain of Anadens, begins to take root in human society. But the possibility of immortality for all does not sit well with those who would rather keep it for themselves. When a conspiracy to sabotage the future of regenesis is uncovered, an unlikely advocate decides to risk his one-and-only life to bring the perpetrators to justice. And amidst all the conflict, the enigmatic Katasketousya have been playing a secret long game with the fate of the universe. Now events race toward a rendezvous with their unfolding machinations, and the resulting collision is going to change everything. \* In Amaranthe, where exotic alien life, AIs, wormholes, indestructible starships and the promise of immortality rule the day, no feat seems out of reach for humanity. But when the worlds of Aurora Rhapsody and Asterion Noir collide and the Rasu horde descends upon them both, more will be asked of heroes past and future. More will be given and more taken, and when the dust settles the very fabric of Amaranthe will be altered forever.

“I save the people who will save the universe. If it can be saved.” After an extraordinary encounter with kyoseil in the Oneiroi Nebula, Nika Kirumase is transformed. Now able to understand and harness the true power of the ancient, primordial life form, she finally has the ability to defend her people—if the kyoseil doesn’t destroy her sanity first. Mesme has long been meddling with the fate of the universe, but the events in the Oneiroi Nebula have exposed its deceptions. A schism erupts between Alex and Mesme over the secrets the Katasketousya keeps—and if their relationship isn’t mended, the world may lose its best chance at salvation. The fractures threatening Concord’s survival aren’t merely personal, and the ramifications of the Ruda’s betrayal in the last battle prove costly to everyone. The Rasu begin deploying antimatter weapons, thereby neutralizing Concord’s greatest advantage, its impervious adiamene warships. Now losing ships, people and planets as the Rasu close in on the Milky Way, Miriam Solovy finds herself short on options and out of time. But Alex has never let those kind of odds stop her, and so a desperate plan is hatched—one that will either save civilization, or doom it to annihilation. \* In Amaranthe, where exotic alien life, AIs, wormholes, indestructible starships and the promise of immortality rule the day, no feat seems out of reach for humanity.

\\THE EXPLOSIVE CONCLUSION TO THE EPIC RIVEN WORLDS SERIES\\ Humanity was granted their time to prepare. Now that it has come to an end, all Miriam Solovy wants is one more day. The Rasu civil war engineered by Alex Solovy and Nika Kirumase has provided Concord the time it desperately needed. Every weapon, every technology, every tactic will be brought to bear in a bid to defend thousands of worlds and trillions of people from annihilation. The enemy that emerges from the civil war victorious is like nothing Concord has ever faced. A boundless legion of Rasu—now interlinked and of one collective mind due to their integration of kyoseil—prepares to sweep across Concord space in a devastating tidal wave. But there might be a way to stop them. It will mean two individuals must take upon themselves the burden of committing genocide, so the innocent beings they protect need never know how such an act comes with a price. “There has never been a timeline like this one before.” A war has been waged for endless aeons. Our greatest champions fight it again and again across millions of years, in a tireless endeavor to save not merely innumerable lives but existence itself. With Mesme’s secret revealed, the enormity of the stakes is clear to all, and humanity and its allies are united as they brace for the return of the Rasu. But the enemy has a secret, too—one that may ensure Concord’s destruction, as it has countless times before. \* In Amaranthe, where exotic alien life, AIs, wormholes, indestructible starships and the promise of immortality rule the day, no feat seems out of reach for humanity. But when the worlds of Aurora Rhapsody and Asterion Noir collide and the Rasu horde descends upon them both, more will be asked of heroes past and future. More will be given and more taken, and when the dust settles the very fabric of Amaranthe will be altered forever.

When she isn’t writing, she’s gaming or working out or getting lost in the mountains that loom large outside the windows in her home. Or she’s dealing with a flooded basement, or standing in a line at Walmart reading the tabloid headlines and wondering who all of those people are. Or sitting on her back porch with a glass of wine, looking up at the stars, trying to figure out what could be up there.
