This book is the best to learn Spanish on your own. It has done wonders for me when I was between 14 to 16 years old. I have just decided to pick back up Spanish at the age of 31 and would love to see this book finally has an e-book edition. Pleeeeeeeeeease somebody, anybody. But I would definitely give this five stars hands down. Well done Mr. John Christopher Pride! Your book is highly recommended.
