In a desperate battle, Earth has temporarily freed itself from the clutches of the deadly Trellixian Empire. Billions are dead and it's only a matter of time before the enemy return. Seeking aid against the Trellixians, two exploration ships are sent out to search the galaxy for allies. If they fail, then the human race is doomed.

The Trellixian Empire was constantly expanding, seeking new worlds for its ever-increasing population. If worlds were discovered with existing sentient populations, they were cleansed to make room for colonization. Hundreds of budding civilizations had been eliminated by Trellixian battle fleets. On Earth, years in the past, a scout ship fleeing from the Trellixians crashed. Scientists investigating the wreckage discovered what the Trellixians had done to the world the scout ship escaped from. They also discovered it was only a matter of time before the Trellixians reached Earth.

The Earth had four fleets to fight the invading enemy. The first fleet valiantly protected earth, but it wasn’t enough. Three fleets would arrive soon and end the threat...but they never came through the wormhole. One ship escaped the massacre, fleeing deep into space while the rest of Earth’s defenses were destroyed. Only the barrier around the planet keeps the enemy from finishing what they started.

200 years ago it devoured Earth. 20 years ago it devoured Gilgamesh. 2 weeks ago it entered our dreams. Al isn’t just a spy, he’s one of the best covert agents alive. At least, he was before everyone in the system started dreaming about him. Now his cover’s blown and he’s out of his depth, scrambling for answers to a mystery humanity has never been able to solve. The Goo. The great cosmic, planet-eating substance that swallowed whole systems.

United we stand. Divided we fall. We stood together once. United. Proud. Humanity was one. Together we colonized the stars. Together we built an empire. That was a long time ago.

Hearts that once blazed with courage now burn with hatred. Meanwhile the true enemy draws ever nearer.

Nuestra existencia está amenazada: las glaciaciones, los impactos de asteroides, la capacidad finita de la Tierra e incluso la lejana pero inevitable muerte del Sol son riesgos de tal magnitud que, si no abandonamos la Tierra, deberemos asumir la idea de nuestra extinción. Por eso, para Michio Kaku nuestro destino yace en las estrellas, no por la curiosidad o la pasión aventurera que los humanos llevamos dentro, sino por una simple cuestión de supervivencia.
