On a mission to the farthest stars, the crew of the Odyssey discovers the impossible: Terra Mirror, a world identical to our own, but with its geography inverted. There, they find not only mirrored landscapes but mirrored selves—counterparts living in a collectivist society that has secretly mastered interdimensional travel. But their arrival is no accident. A decaying anomaly, a byproduct of their counterparts' experiments, now threatens to collapse both realities into oblivion. Forced to confront versions of themselves shaped by a different history, the Odyssey crew must forge an impossible alliance with the very people who endanger them. They must grapple with the nature of their own identities, redefine what it means to be human, and decide if one Earth must be sacrificed to save another—or risk watching as both are erased from existence forever.

For millennia, the moon has been humanity's silent companion. But it is not a world of rock and dust. It is a lie. When seismic quakes crack open its surface, they reveal the truth: the moon is an ancient alien construct, an observation station built to monitor Earth's evolution. An elite international team ventures inside, only to awaken its dormant systems and a terrifying fail-safe protocol. The station's creators, the long-extinct Obsidians, were not just observers but custodians of a delicate cosmic balance. Now, their automated legacy has put humanity on trial. Faced with global annihilation, the team must decipher the secrets of their silent guardians and prove humanity is worthy of survival before the moon itself becomes our executioner.
