Isso soa como uma série de livros de Richard Fox chamada A saga da guerra de Ember
In the near future, an alien probe arrives on Earth with a pivotal mission: to determine if humanity has what it takes to survive the impending invasion by a merciless armada. The probe discovers Marc Ibarra, a young inventor who holds the key to a daring gambit that could save a fraction of Earth's population. Humanity's only chance lies with Ibarra's ability to keep a terrible secret and engineer the planet down the narrow path to survival. Earth will need a fleet. One with a hidden purpose. One strong enough to fight a battle against annihilation.
A série tem cerca de nove livros (começando com o título The Ember Guerra ) e gerou algumas outras séries menores.
