One day the Andromeda galaxy will collide with ours. What if it was deliberate? What if the impending collision has been speeded up, so that it will threaten the whole civilisation in the Milky Way and destroy them all? What will the Council of Worlds do to prevent this happening? If the Kresh and the Gnathe have been travelling back in time to rescue alien civilizations from the deliberate destabilisation of their stars, before the Harvester can feed on the extinguished life force, an ancient enemy has been formed! To combat this menace, a search through time is instigated to find those who waged war against the Goss. The galactic civilization of the Milky Way move stars and worlds into a globular cluster and launches it towards the greater Magellanic cloud to escape the impact of the galaxies leaving the time-fished aliens to face the Harvester. Link-soo-shan gets involved with genetically engineering a new type of human being that can see into the future. Kamiel sends an expedition composed of useful aliens, to the Andromeda galaxy to free the intelligent species living there from the yoke of the Harvester. In doing this he creates potential world minds and in doing so, he creates a galactic society bound by the telepathic abilities of the Goss that can control wormholes. In time he launches an armada of Toarvaks against the energy being that feeds off the life force of sapient species.

Genesis Debt is a sequel to Genesis 2. Long after the sun has entered its red giant stage, the human race is recreated by nannite Guardians on a Jupiter that has had its great gas mantle stripped away. Instead of a gas giant the nannite crew find a seeded world teaming with life on a super continent that stretches from pole to pole. Several years after the defeat of the Tyrant, Ender-whann-soo’s Brood-mother daughters devise a way to reach out to the people of Earth six million years into the past. In doing so, the riddle of the Gnathe’s existence on Jupiter will at last be explained and the possibility of saving the human and ape civilisation from the danger of the expanding sun become a reality. To do this will mean using the airship again to find a large time-distorting crystal that was once hidden under Jupiters Red Spot. The resurrection of the deposed Empress can lead to an alternative reality that could create a paradox in time. The blood debt of the Gnathe will be paid in full or Link-soo-shan’s revenge will destroy them all. ‘The Genesis Debt’ will be paid by the Gnathe.

There is a machine intelligence left over by the Harvester’s actions that is settling solar systems and obliterating life, in its expansion of territory. An alien people sent self-replicating probes to planets orbiting nearby stars and never had the chance to settle these worlds. The sentient survivors of the war against the Harvester form a strange alliance with one of the Collectors to try and defeat the Janis probes. This being becomes the ‘Farmer’ that spreads sentient life so that it can absorb and store them for a purpose of its own. In the past, one hundred thousand light-years away from where the Harvester slept uneasily something watched the wormhole activity with curious senses. The plan had been to cannibalise the replicated probes and the mining machines when the Janise had developed their own interstellar ships and had arrived at the prepared world. The Harvester had exploded their sun before they had any chance of doing this. Toarvaks had slipped through the life barren systems it dominated and out of sight using wormholes. They were seen and recorded with the information sent back. The central intelligence had no knowledge of wormhole technology as it relied on psychic power to open one. So it patiently waited and built a flytrap.
