Acceptance was the slowest going for me so far in this series. It's well written, and interesting to be presented with the new perspectives on the characters. What you thought you knew in the previous books were likely lies, half truths, misunderstandings.

Frankly, I'm not even convinced that I know what happened at this point. This feels like the sort of series that would benefit from another read through at the end.

What Area X is doesn't matter, what happened to the Biologist or Saul or Grace also doesn't matter. Everything so far feels incidental, as back up singers for something we haven't even seen yet.
