I finished "Gods of Night" today and enjoyed it quite much. It's certainly a good setup and I'm eager to see how the plotthreads develop and come together.
The only thing I didn't agree with that much was the Deanna-subplot. I seriously doubt Ree's qualifications as a chief medical officer. While not everyone can deal with everything properly, he should have seen that he was quite unskilled in dealing with Deanna's problems, and thus should have refered her to another doctor on Titan (he can't be the only one after all). It's appalling that she wasn't really given time to come to terms with the diagnosis and think through her options. And from a purely medical point of view, I didn't quite understand the haste Ree was trying to enforce...
But well, let's see what happens next (in this plotthread and all the others).
I'm looking forward to #2.
