I really wanted to like this book. The story concerns several people on a mission to Pluto to find out what the aliens left for us.
It could be a great story. However, it reads like the kind of story I'd have written in high school, fifty years ago, but at least I would have got the science right. I would have understood how Neptune orbits, I would have remembered the speed of light (it takes four hours for light to reach Neptune from Earth), and if Charon had been discovered just a few years earlier I wouldn't have forgotten that Pluto has a moon.
As it is, between info dumps, narrative speed bumps, terrible descriptions of interpersonal relationships, and the bad science, I had a really hard time finishing. I skipped a lot of text just to keep going, and how sad is that? Not recommended.
