Dessler, supreme leader of the Gamilas, steps onto the stage to rally his people, even as the Yamato departs on its desperate voyage to Iscandar. Soon the ship will be out of real-time contact with Earth, and the crew transmits messages homeward to their families--and unless they return, these will be the last. Making a final stop at Pluto before interstellar space, Captain Okita finds that the Gamilas still consider it planet enough to have placed an advance base there...for Earth's invasion!
The alien Gamilas have devastated the biosphere, determined to reshape our planet into their own new home. But a third force has intervened, as an emissary from the distant Iscandar has given humanity the plans for a faster-than-light drive. If the Yamato can battle its way through the Gamilas fleet to reach Iscandar, their technology can heal the Earth--but the odds against us are literally astronomical...
