Looks like I'm not going to finish it. It was moderately interesting but just wanders around too much. Physically and literarily.
1) The two main (perhaps? see 2) characters are off the moon by 30% and then back there by 50%. Seemed to have less to do with the moon than with China, which is fine. I guess that is half of the title! But not why I was reading it.
2) Many POVs and I often can't tell who is talking. Multiple 1st person (don't tell Chuck!) with foreign chapter titles (don't tell Geoff!) made it difficult. I have little doubt they will all come together (some already have) but don't have the patience to keep reading.
