At the end of Unconquered, the first book of the trilogy, Canadian teenager Victoria has survived her perilous journey to China to extract her biological parents from exile. Along the way, she uncovers some of China's most mysterious historical secrets. As life returns to normal for Victoria back in Canada, a confluence of disasters suddenly pummels Earth, a premonition of the apocalypse about to befall humankind. An immense armada carrying scores of millions of female warriors from the red giant Betelgeuse has arrived at the outer reaches of our solar system. They plan to exterminate all humans on Earth and colonize the planet.

With the help of a toy robot and a quantum gateway in the form of a mirror, Victoria visits the paradise planet Shangria, where an invincible one-eyed hero ends the Endless War, but, tortured by an unrequited love, inadvertently causes a temporal rift only Victoria could repair by the Great Reset. The Canadian teenager also pays a visit to the Amazonian planet to learn about the origin of the female warriors, the history of their struggle, and why they want to take over Earth.

Lost in the labyrinth of the past after being betrayed, Victoria must find a way back to the future because she is the only person capable of stopping the alien invasion and resetting the universe. By coincidence, she meets the author of Dream of the Red Chamber, one of China's four greatest classical novels, and unlocks some of the book's most enigmatic mysteries, one of which helps her return to the present timeline.

Halfway on her homeward journey, Victoria stops by the banks of the Danube to witness an invincible general, who also happens to be an early founder of Canada, win a decisive victory in one of the greatest battles in European history. She realizes what is most important to her and refuses to abandon the human race, though knowing she has little chance of saving it. Will Victoria risk everything on a fool's errand?
