Ohhh Epic. EPIC. epic.
This is the payoff. 31 books into this series, this is great. I want to say it's the best of the series, but I'm also looking fondly back at a few others that might qualify.
...but this one was good. Way good. Worth-slogging-through-books-1-to-30-good.
We get to see some old friends, old enemies, and everything seems to culminate in this book. There's a season of Dr Who that was like this for me-- just when you thought it couldn't get any bigger and more awesome, everything kept building and getting more and more epic. (can I say epic for the fourth-no-fifth time in a review? I'll stop)
Ok, spoilers ahoy. Big spoilers ahoy:
