Haven and earth

A terrifying secret is discovered lurking in the outer reaches of the Solar System…a failed star, seventy times the mass of Jupiter, which is hurtling towards the inner planets, and will destroy Earth by the year 2100. With less than a century to spare, governments on Earth mobilize all their resources to build arks that will serve as new planets for humanity. Venkat, a computational neurologist living in USA, proposes a backup solution: Send Seedships containing only the AI created by him into the galactic neighborhood. Free of all biological constraints, each Seedship can travel for millions of years, find a suitable planet, terraform it, and then recreate humans on that planet, ensuring humanity's long-term survival. On Haven, ten million years later, where Seedship 53 has established a thriving human colony…two lovers, Adam and Meem, confront another threat. In the middle of a genocidal war between their rival tribes, they race against time to discover the reason for a strange mental plague that threatens to wipe out all human life on Haven. But as they dig deeper, they realize that the AI that came with the Seedship may be the cause – as well as the cure – for this plague. Across a gulf of ten million years, Venkat's thought patterns, encoded within his creation, may now hold the key to the survival of what may be the last human beings left in the galaxy…
