I'd call it a collection of blog posts / articles more than a typical book. Articles are of good, quality, without usual marketing fluff and (what is important for non-tekkies) without technical jargon. The most useful part is definitely the one about decentralised systems economy - its non-obvious risks & opportunities. This book doesn't try to build up crypto-currency hype (like 95% of similar books ...) - which is definitely a big pro.
The are several important aspects that I think are still missing - about organic nature of ethereum ecosystem, about private blockchains & their applications, about challenges of "transaction-ness" in consensus-based systems.
One final big pro (worth 0.75 star) - great reference table (links to sources) at the very end of the book.
