A file from the Interplanetary Data Stream... When the first ever space cruise ship completes its inaugural tour of the solar system, Bellatrix 'Bella' Starr will catch a ride back home that she'll never forget. The ship docks at its final destination, a space travel corporation's half-moon beach hotel orbiting the gas giant Neptune. But the corporation's latest drug cocktail for countering microgravity threatens everyone on the ship and the beach resort. A flaw in the treatment program, along with a gravity drive that produces a strong magnetic field, transforms all but the immune into bloodthirsty living zombies. On the faster return trip, Bella Starr and a group of immune passengers must navigate the dark corridors of the ship and find a way to warn port officials of the impending apocalypse before they reach Earth, and if all possible, live long enough to see the planet they call home.
