Ancient machine intelligences. Resurrected species with no memories of the past. Creatures composed of gravity strings. What is hidden in the void between galaxies? Tapache, a machine intelligence with great power, has revived the Roranian people from their derelict remains. It has gifted them the Great Ship to voyage through space and given them a purpose: to discover the truth about a weapon capable of unthinkable devastation. An unexpected attack, followed by hundreds of years in stasis, scuppers those plans. Hope seems lost for a small group of Roranian survivors, until something far greater draws them in a megastructure beyond comprehension. The megastructure is far from safe. There are incumbent species that already lay their claim, all with secrets of their own, and a strangely smart information network that exists where it has no right. Was Tapache lying?
