Nancia is her name, NX-928 her designation. Enter a future world in which brains are connected to computers to help run cities and ships; brainless bodies or brawn do the physical work. In the second book of the Brainship series, a new "shellperson"—someone born with grave physical disabilities that required her human body to be encased in a massive titanium column—is provided a direct link between her mind and the computer of her ship, XN-935. Nancia is now a brand new member of the elite Courier Service of the Central Worlds, the "brainship" of the most advanced interstellar ships around. But her innocent vision of human nature is shattered on her first voyage. Nevertheless, the idealistic Nancia and her worldly-wise new "brawn" partners must band together to save the galaxy.
