One of Powell's top ten spaceships in fiction, as shared at the Guardian:
Children of Time by Adrian TchaikovskyRead about another entry on the list.
Due to a technical blunder, the last humans alive find themselves confined to their starship for centuries, while a different (and surprising) Earth species grows and evolves on the planet where they wanted to settle. Generations grow and wither in the corridors and cabins, while a few survivors of the original crew sleep in suspended animation, observing the same mistakes of power and aggression being played out again and again. Yet all the while, the ship remains a constant and unchanging presence around them, keeping them safe as the centuries pass.
Children of Time is among Spencer Ellsworth’s five top works of SF that turn weird bug behavior into great fiction.
