Query: intriguing and confusing

I bought this book after reading the author's website and listening to a recorded interview of her views on the 2012 benchmark.She sounded highly cogent, intelligent, sensitive and serious.I could not understand most of what she was talking about in this book; there were too many references to matters I'd never heard of before; this process continued throughout the book so that by the end I had no idea at all of what she was discussing.
