Outstanding sci fi story. Fascinating! I’m not the only one who thinks so either. It’s part of Good Reads best sci fi fantasy books of 2018. The audio book is outstanding. Each character is played by a different voice actor and very well. I don’t always like a lot of scientific detail (like The Martian), but the bit of science in here was fine and sailed past interestingly enough when read to me. I have read the whole series and it’s one of my faves for 2018.
