Blue Remembered Earth (Poseidon's Children #1) by Alastair Reynolds ★★★★★

Un-for-gett-able. 

A new millennium foundation work of solarpunk and afrofuturism.  It’s hard to believe this has not been snapped up and made into a series.  Fools! 

‘Poseidon’s children,’ he repeated. ‘Is that supposed to mean something?’ 

‘We came through. That’s all. We weathered the absolute worst that history could throw at us, and we thrived. Now it’s time to start doing something useful with our lives.’ 

‘And I know what it feels like to imagine going further. To hold that incredible, dangerous thought in my mind, if only for an instant. To think: what if I don’t go home? What if I just keep on travelling? Watching that pale-blue dot fall ever further away, until the darkness swallowed it and there was no turning back. Until Earth was just a blue memory.’ 

Unforgettable
