Solid writing, great tone, and consistent themes. In the end there are a few too many tiny threads (pun intended) left for this to reach a full five stars. 

It was also a bit too blunt towards the end, in that insecure sort of way authors do when they aren't sure if their point came across without making it explicit at the end. It's a shame because this book and its theme and message came across so clearly without the explicit statement.
