On the first page of this book we learn exactly what Harry Dresden's mission and prime focus is going be. Throughout Changes the characters we know and love appear, but the conversations they could/should and probably will have with Harry one day often don't eventuate, because there simply isn't time. Harry has his mission and one sole focus and his friends are either with him or not. There is no time for deep discussions or reflections.
The changes, questions and possibilities accumulate in this book, not just for Harry but for all the characters. I can't wait to see which avenues Jim Butcher will explore now that so many more have opened up. But fans may also be surprised at some of the Dresden familiarities that come to an end.
The final 20 - 25% of this book especially impressed me. It was building up to a huge climax and it certainly didn't disappoint, but we are provided with many surprise twists rather than just one big fight at the end.
There is one particularly enormous WHOA! moment that I guarantee nobody will be expecting.
A wonderful book, a crucial pivot point in the Dresdenverse and after I've taken stock and recharged the kindle I'm off to read it again to see what I missed.
