Hard going. Seemed to lack a clear direction. Diagrams/ timelines/different typefaces and tables would have made it easier reading. The details are there but difficult to retain page by page with few key points or summaries. It was hard to work out where the writer was heading and what point was the writer aiming for. Some info seemed unnecessaryand info was sometimes repeated. Fancy words were distracting sending me to the dictionary only to find a far simplier word would have sufficed. I wasn't impressed. A disappointing read but I may not be the target audience nor have enough background to get the most out of it. It's still worth a read. Well done to the writer who put in so much work.I learned new things.
