This book is a thoughtful presentation on why reading in English is difficult, and on page one Diane looks at other language from around the world in which children acquire more easily and earlier than English. A relationship to the Alphabetic code is made - and then discussion on how to better help both early and later readers learn skills to deal with the English Language.
As in the compliment to this book (see: Language Development and Learning to Read: The Scientific Study of How Language Development Affects Reading Skill (Bradford Books)) dyslexia is also mentioned in perhaps a new light - that it is not biologically based: "For a biological theory to be accurate, dyslexia would have to occur at the same rate in all populations" but it does not (p 3).
It looks at writing systems and the history of and then gets into the nitty-gritty of how to teach reading. It breaks down pedagogy on many levels and is not just academic literature developing theory - but using theory that exists it provides ways to apply sound pedagogy.
If you are interested in teaching reading - obviously you are if you are reading this review - I would recommend this book without hesitation.
