Very disappointed by this book unfortunately. Reading the blurb and recommendations, I was very excited to try it, it seemed like exactly my sort of thing. However, I am now 90 pages in and thoroughly bored. The topic of discussion is often erratic and tenuously related to the subject at hand. For example, one recent chapter spent several pages unfathomably concerned with bluejays and horse flies, which no bearing on the topic of the chapter until the very last paragraph, when a clunky metaphor was drawn.
The book honestly reads like Perry had a great idea and wrote about 50 pages of quality stuff, but then had to dilute it with flounder to make it up to a sellable 240 pages.
