A weapon of unimaginable power. A desperate mission to the center of the galaxy. Mankind's fate hangs in the balance.
Captain Thomas Holbrook has anguished on the thought of drawing a one-way mission. When he receives orders to divert his warship to the center of the galaxy, a region from which no vessel has ever returned, he comes face-to-face with his greatest fear.
It's the year 2330. The "aughts," robots that warred for independence from mankind, seek insurance against the ever-present human threat. An aught ship speeds to the galactic center for material to build a weapon that could destroy the Earth.
Holbrook can't allow the creation of a planet-killing bomb. He enlists the help of a brilliant physicist with her own reasons for joining a mission that may not return, and an aught informant who might be a double agent. Can he keep a mutinous crew at bay, stop the aughts at the center of the galaxy, and somehow find a way back home?
