Born into a world of cleaning houses and unaware of her cosmic lineage, Jupiter Jones faces a mundane life filled with earthly struggles until her reality is upended by the arrival of Caine Wise, a genetically engineered ex-military hunter. Caine bears the news that Jupiter has a genetic signature marking her as the next in line for an extraordinary inheritance that could alter the balance of the cosmos. Her existence threatens the reign of the powerful Abrasax family, the royal dynasty that controls many planets, including Earth.

As Jupiter is thrust into an intergalactic society, she must navigate a complex web of alien politics, power struggles, and family feuds. The Abrasax siblings, Balem, Kalique, and Titus, each with their agendas, vie for control of Earth, seeing it as the key to their wealth and power. With Caine's aid, Jupiter embarks on a dangerous journey that will challenge her understanding of the universe, force her to confront her destiny, and determine the fate of the planet and her own future.
