I am currently around 200 pages into reading Children of Time by Adrian Tchaikovsky and enjoying it quite a bit. I loved the first part of it, but it has lost just a little bit of momentum.

I received it as a gift from my brother, who knows my literary tastes probably better than anyone.

This question is set to close in 30 days, but I will probably finish the book and rate it in the next two weeks.

For reference, below are my Goodreads ratings for most of the sci-fi books I have read in recent years, plus some relevant nonfiction.
