2.5 stars. The organization of this book is ultimately where I struggled the most. The timeline jumps around quite a bit and the story doesn't stay linear. Likewise, the experiences aren't grouped together in any kind of order. It felt quite random and a bit rambly. There is some good insight in here and the emotions are certainly presented well, but it didn't have a lot of cohesive structure for me. The mix of memoir and science was interesting and I did come to actually like that construction device, but I had a hard time teasing out solid thoughts as major premise points. This wandering type writing continued to the conclusion, which somewhat drifted off to an ending. I was left feeling rather unfulfilled, somewhat left out to dry.
