This book was my constant resource during my masters degree course in TESOL. No other book was more helpful and clearly written! If you do much reading in the field you will know that there are a great many authors in the TESOL field whose writing style is immensely dry, convoluted and tedious. Not so here...By all means get this book! You will certainly not regret it.
