Spiders and ants and human beings, Oh My! Adrian Tchaikovsky massive work of science fiction won the 2016 Arthur C. Clarke award for Best Novel. An award it deserved. This book is an important work for science fiction fans missing the fanciful, yet probable, speculation Arthur C. Clarke made famous. Children of Time both accepts the hard science of space travel and challenges your understanding of intelligence and awareness.
Reviews of Children of Time put it in the hard SF genre. I am not a fan of hard SF. I find it boring. The endless speculation of characters turns into pages of exposition to support the fanciful ideas of the author. Clouded story arcs vanish beneath the weight.
When a good story breaks through the speculative science, I find that physics and time preoccupy the genre at the expense of biology. Stories span thousands of years, but through magic hibernation chambers or trippy time dilation, characters do not age, or age in a manner somehow unimportant to their psyche or the story arc. Folding space might be impossible, but I used it in The Fundamentals because preserving a body in a hibernation chamber for thousands of years is impossible. Now consider Children of Time.
