This is a (very) light primer to the new features and APIs of HTML5. It was an enjoyable read, and Pilgrim's style is great, but I probably wouldn't recommend this book to most, because it was published so long ago... Unless they really do just want a very basic overview of things like the History API and the new form helpers. It seems as though this book was designed as a reference someone should just skim, because Pilgrim repeats many parts of his explanations throughout a single chapter (or throughout the whole book). I really enjoyed the discussion on standards, however; it was a great recap of the events that led up to the HTML5 standard, and definitely taught me a lot about the culture of web standards. In all, not the greatest book, but a fun, fast, and easy-to-follow read. Just be aware of its publication date.
