Viviana Wells is nothing if not a survivor. Maybe that doesn't make her so different than the Anokhian aliens, who invaded earth for one sole purpose... Survival.

When the UNSC Pillar of Autumn escapes the glassing of Reach under heavy Covenant fire, a blind emergency slipspace jump sends the ship far off course. Instead of finding Installation 04, the vessel is torn across dimensions and plunges through the atmosphere of an unknown, uncharted world. In Westeros, the Dance of the Dragons has begun. Blood, fire, and ambition threaten to tear the realm apart. When Captain Jacob Keyes establishes Alpha Base from the ship's wreckage, the arrival of 26th-century military technology, powered armor, and UNSC Marines alters the calculus of the civil war overnight. But the Greens and the Blacks aren't the only ones caught off guard. For the UNSC, giant fire-breeding reptiles are an entirely new kind of strategic threat.

In a world built on political games and bloodlines, the Master Chief doesn't care about the Iron Throne-he only cares about keeping people alive. Two civilizations collide. The stars remain light-years away. And a new kind of history begins.

It's the day I've feared for most of my young life. It's my fourteenth birthday. Why have I feared today? You ask. Today, I am being drafted into the International Army Coalition. My name is Sage Turner, and today, I am going to war. In 2080, the Earth is at war with an alien race known as the Galanala. Most able adults had either died in the war or were too disabled to fight. Millions of teenagers are now fighting in this war. It is now on us to win this war for the sake of humanity.

When a multiversal rift tears open above King's Landing during a night of storms, a starving, liberated alien parasite crashes directly into the ancient godswood of the Red Keep. Drawn to the strongest well of repressed rage, crushing duty, and quiet hatred in the castle, the Carnage symbiote chooses Queen Alicent Hightower as its host. What begins as a subtle, secret infection rapidly devolves into a dark, romantic union of body horror, religious fanaticism, and absolute power as Alicent surrenders every restraint to a voice that offers unconditional devotion. As the Dance of the Dragons erupts, the political war for succession is swallowed whole by something far worse than dragons. Through the asexual budding of its biomass, the symbiote brings forth two terrifying offspring-Scorn and Raze-transforming Alicent's fierce, twisted maternal instincts into an unholy, unstoppable dynamic. Together, the Blacks and Greens alike come to realize they are no longer fighting for a crown; they are facing a cosmic predator, its bloodthirsty thralls, and an unyielding Red Family seated upon a living throne.

Shinpachi and Kagura are sent into the future and discover that it is darker than usual.

When a violent dimensional rift hurls elite Viltrumite warrior Anissa into the skies of Earth-92131, she expects to find a familiar universe and her target, Mark Grayson. Instead, she finds a world defended by mutants-and an omega-level powerhouse who can match her blow for blow. Rogue's absorption touch is the only force on this Earth capable of grounding an unyielding conqueror. Thrown together by escalating Sentinel threats and multiversal instability, two apex predators caught in deep emotional isolation must forge an uneasy alliance. What begins as sheer hostility slowly unravels into a dangerous, high-stakes collision of power, vulnerability, and quiet understanding. When the rifts finally seal and the war is left behind, they face a choice: return to the cold isolation of empires, or stay in the quiet sky they built together.

When the sky splits, empires fall-and two queens of different worlds find themselves trapped in the wreckage.

Mileena is the fierce, lethal Princess of Outworld, a warrior whose beautiful facade hides a rotting, monstrous secret. When a multiverse incursion forces them into a brutal tournament for the fate of reality, they are meant to be rivals. They are meant to kill one another. But in a match of steel and desperation, the impossible happens. A single wound, a lethal infection, and the blood of a Targaryen is irrevocably tainted by Tarkat. Now, Rhaenyra is no longer just a dragon. She is a hybrid of fire and hunger, bonded to the very woman who was supposed to be her doom. As gods watch and their respective worlds fracture, the Queen and the Princess find themselves caught in a dangerous, obsessive dance. They are caught between the weight of their crowns and the terrifying, magnetic pull of the infection that binds them. In a multiverse that demands they sacrifice everything, Rhaenyra and Mileena decide to tear it all down instead. They were meant to be enemies. Now, they are the only things left that are real.

Within days, Oliver and a woman he barely knows are ripped from their lives and strapped to examination tables inside a featureless white chamber.
