An OK overview, not too much hype. However, the explanations are often so brief that the more complex standards (BPEL4WS being a particular case) would be impossible to understand if I hadn't read the official documents. The figures are plentiful and often awful. Many have little connection to the text that references them (13.2, 15.1, 15.2 being good examples). Entities in the figures are not explained in the text, and the text uses terms that do not show up in the figures. Also, anyone who includes a six-page listing of XML syntax without any kind of structuring, enhancement, or occasional word of explanation (e.g., listing 12.1) should be pilloried. Despite the fact that this has become some sort of sport, XML syntax was not designed to be read by humans in great quantities.
The style was a bit too chummy for my taste but perhaps that is what makes the books acceptable to nontechnical people? And the author should really find another favorite verb instead of "leverage". He employs it instead of "use", "implement", "incorporate", "include", and some more words, all of which would be either shorter or more clear (I thought I even spotted a couple of cases where "provide" seemed intended). By page 200 it gets to be a major irritation.
