Very interesting. The writing style is somewhere between casual and academic, which makes it quite easy to read most of the time. While--as a few reviews have already pointed out--it is from the perspective of a witch (making biased in that direction) and is quite speculative at times, the author is honest and upfront about these things. For a book that is about such big, abstract concepts of quantum physics and reality, I find it to be a surprisingly concise and evidence-supported.
