I just got through the first third of the book....year zero. I need to take a break and absorb all the threads. The end of this section reminds me of the end of the Wolgast/Amy section in the first book. I'm a little melancholy right now over the fate of one of the characters. It's fitting but sad. Cronin is so good at writing characters and back story and he's tying things together nicely. Loving it so far.
