Query: This book is great!

Of all the books I have tried for learning French on my own, I like this one best. The instructions are clear, the material is interesting - and useful - you learn to say exactly what you need to say in everyday life. The pronunciation and spelling guidelines presented are very helpful. I am pleased at how much French I have been able to learn without taking classes. Thank you, Mr. Mercado!
