Query: I have not found one better

Let's face it. Learning Thai is not easy regardless of the teaching method. This book however was exactly what I was looking for as it also teaches how to read and write the language. I found some mistakes and the audio is not cooridinated very well with the book but you will have to losten to it MANY times anyway in order to ever learn it. After a few times you learn to find the corresponding section in the book. So, all in all the book is well worth the money and it does what it says it will do.
