Query: Not exactly a well-edited page turner

While this book will deliver a comprehensive history of the various Crusades to the reader, the editors must have been second year English students. One of the most obvious examples is where, within eleven lines, the exact same wording describing a particular castle is used. Great for Alzheimer patients, but otherwise unnecessary. On the other hand, archaic terms go unexplained as if we're supposed to be conversant with every aspect of Christian practice in the first milliennum. Word choice is sometimes overly academic, so keep your hardcover dictionary nearby. That said, I learned quite a bit about the Crusades from the book, but it probably could have been written in a much more erudite fashion.
