Bellatrix

At the conclusion of Unconquered, the first book of the Planet of Perpetual Peace trilogy, Canadian teenager Victoria has survived her perilous journey to China to reunite with her biological parents. 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 Armageddon about to befall humankind. An immense armada transporting hundreds 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 dimension-tunnelling catoptron, Victoria visits the paradise planet Shangria, where an ingenious one-eyed warrior ends the Endless War. However, the tragic hero inadvertently causes a temporal rift, threatening the destruction of the universe. The trouble at Shangria reaches Earth through Betelgeuse, where a race of female warriors known as Amazons overturns the patriarchal rule of their planet and, by a twist of fate, discovers Earth as prime real estate for a colony.

Trapped in the labyrinth of the past without her fancy gadgets, Victoria must find a way to get back to the future, as she is the only person who can stop the alien invasion and reverse the temporal rift. To escape her predicament, Victoria visits the author of Dream of the Red Chamber, one of the four greatest classical novels of China, and unlocks some of its most enigmatic mysteries, one of which helps her return to the present timeline.

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