I bought this book to lears how to play traditional spanish styles on my concert guitar.
The book is very considerably, if you do every lesson properly you will have work for sure more then a year and really learn a lot.
I am not a beginner at guitar, normally i am a bass player, and the difficulty was very matching for me. The beginning is quite simple finger lessons, but it gets more difficult very quickly. You should already be able to play guitar, this book is not for absolute beginners, this would be frustrating.
There is a CD delivered with the book, here you find all lessons to play along or to just listen how it´s played correctly ;)
But this CD ist not readable by all devices. My Notebook and my Desktop PC did´nt want to play it.
So all in all this is a very good book with very good lessons and a competent tutor.
