Old Captain Orbus commandeered a ship to flee Spatterjay, desperate to escape the violent planet. Orbus's alien enemy, the Prador Vrell, is also moving on. The Spatterjay virus mutated him into something even more dangerous. And he's hunting the Prador King himself - who sought to kill him, to bury the secret of their similar transformations.
Orbus and Vrell clash in the Graveyard, a lawless zone where the Prador have seized a key space station. Official action by humanity or Prador would end peace, as a centuries-long cold war simmers. So Earth commands Orbus to destroy the station, even as the King recruits a monster to exterminate Vrell. But their actions will awaken an intelligence that annihilated civilizations, as it stirs after five million years . . .
