A decade after the end of a devastating insurrection within the android community on Alpha Home - a planet in the Alpha Centauri system that is doomed to crash into one of the suns - humanity and androids work together to find a new home for them, But this isn't as simple as it might appear, because the androids have been persecuting humanity for millennia and there is significant resistance to full integration. In a story that ranges across the galaxy - and human relationships between themselves and the product of their creativity - we also encounter xenophobia and alternative forms of government that might be a way forwards.
