Query: THIS edition is terrible.

Five stars for the content of the book, no question. But this particular edition is ridiculous - the copy-editing is AWFUL, with typos too numerous to count, and several formatting errors as well. Note that this isn't a standard paperback-sized book either, but an unnecessarily bulky edition with an awkward typeface to boot. Buy this book - just buy a different edition of it.
