For many billions of years, humans—having conquered the curse of aging—spread throughout the entire Milky Way. They are able to live all their dreams, but to their great disappointment, no other intelligent species has ever been encountered.

They have only one hope: The 'Rescue Project' was designed to feed the black hole in the center of the galaxy until it becomes a quasar, delivering much-needed energy to humankind during its last breaths. But then something happens that no one ever expected—and humanity is forced to look at itself and its existence in an entirely new way.
