Now grown, Jupiter dreams of the stars but wakes up to the cold reality of a job cleaning other people's houses and an endless run of bad breaks. Only when Caine Wise, a genetically engineered ex-military hunter, arrives on Earth to track her down does Jupiter begin to glimpse the fate that has been waiting for her all along - her genetic signature marks her as next in line for an extraordinary inheritance that could alter the balance of the cosmos.
