Retribution

The Martian Saucer Fleet, built using hyperdrive technology supplied by the alien emissary, is ready! The human pioneers of Mars will launch against the Masters-evil Reptilians who attacked humanity once before from another solar system. And if the human fleet can free the emissary's enslaved Chontroon race from these overlord Masters, the two races will combine forces to prevent the Reptilians from spreading their villainy across the galaxy. Confident they are prepared, the Martian forces hurl themselves light years away. But all is not as it seems-with them is a traitor bent on stealing a saucer. And if, in the resulting chaos, the Masters capture a ship, the Reptilians may use the drive's space-time power to alter history, even if it initiates a time paradox. When the settlers left behind discover the danger, they devise a desperate attempt to warn the fleet. With the use of an unreliable relic and a reluctant pilot, old friends reunite for a gamble that will test their resolve and courage, especially when they uncover the traitor's identity. In this, the exciting conclusion of the Martian Manifesto trilogy, humans and aliens battle to determine the fate of worlds while time itself hangs in the balance.
