From the author of The Forever War comes the Worlds trilogy finale: the last of humanity faces extinction on a doomed voyage to a new home in the stars. The Earth is no more, an uninhabitable shell following the one-day war that obliterated the population. In the decades that followed, the surviving Worlds orbiting the dead planet have become the last refuge of humankind. With the discovery of a possibly habitable planet in a distant star system, ten thousand brave colonists are preparing to depart from New New York aboard the interstellar vessel Newhome. Among them is Marianne O'Hara, who will ultimately control the fate of what remains of the human race. The momentous voyage is plagued from the start by ignorance and sabotage, and by the dark tenets of a nihilistic religion dedicated to ultimate destruction. But despite the many trials and tragedies, the spacefarers--and particularly Marianne and her loved ones--will be forced to endure. There is no turning back once the journey begins . . . for soon there will be nowhere left to return to.
