I have this book for over a month and it never leaves me. This book has really been carefully thought out, passing from one lesson to another without leaving any shadow. I can not find all the missing audio CD (except maybe if you want a super pronunciation, and again ... Anyway, one thing at a time, first learn!) Anyway I serve, I am making progress every day, it's really fascinating! Buy it, I doubt you could do better for a beginner.
