The acclaimed writing team of Barton and Capobianco return with a riveting and provocative tale of a doomed future and a last desperate attempt to salvage the human race. In the year 2083, with the Earth poisoned beyond repair, the search for new worlds to colonize has proven unsuccessful. Two renegade family units -- a microcosm of the hopeless, self-destructive society they have fled -- have rocketed into the heart of a mysterious alien culture that has created a godlike entity for the purpose of preserving all life. But to accomplish its goal, an ever-expanding would-be savior that is omnipresent in time must first absorb the past, present and the future of the universe. In humanity's final moments, the flawed representatives of a near-dead world must find the key to their species' survival -- even though it may already be too late...and may always have been.
