Children of Ruin expands the universe of Children of Time by following a terraforming mission that goes very wrong and creates another completely unexpected form of intelligence. Much of the story revolves around the discovery of an alien ecosystem, the people who tried to shape it, and the later consequences when different species finally come into contact.

The book has a bigger horror element than the first one, especially once the strange parasitic lifeform enters the story. It still has the same fascination with evolution, intelligence, and communication, but it feels darker and more dangerous. The ideas are huge, the world-building is excellent, and there are several moments where the story becomes genuinely unsettling.

The Goods

  • Excellent alien world-building
  • Very strong evolutionary ideas
  • Good mix of science fiction and horror
  • The alien intelligence feels truly different
  • Expands the series in a meaningful way

The Bads

  • Can be dense in places
  • Some sections move slowly
  • The timelines take a little adjustment
  • A few characters feel less memorable
  • The science can get complicated

My Recommendation

This is a great follow-up for readers who loved the big evolutionary ideas in Children of Time but want something stranger and more unsettling. Children of Ruin pushes the series into darker territory with genuinely alien forms of intelligence and a much stronger horror element, while still keeping the science and world-building at the centre. If you enjoy ambitious science fiction about evolution, communication, and what happens when completely different kinds of life try to understand each other, this is one of the strongest books in the series.
