THE FOURTH SEED OF THE FIRST SPECIES: Three Alien Civilizations were erased. The Fourth Seed is on Earth.

Beneath the surface of the Moon, an impossible body has been waiting for thirty- one years.

It is not human. It is not dead. And it does not belong to any species ever recorded.

When a secret program summons a xenobiologist to an extraplanetary base, the discovery opens a fracture in the history of intelligent life. The traces lead toward an unprecedented truth: three alien civilizations have already vanished, and the fourth seed of the First Species may have taken root on Earth.

Among clandestine laboratories, powers that manipulate silence, and intelligences older than the stars, the fate of humanity becomes entangled with a final question: who seeded life, and why does someone want to erase its memory?
