Query: Learning Portuguese

The book is broken into small sections, which makes it easy to learn. The way its written and the appearance of the book makes it inviting instead of intimidating as most language books come across. The best part is that every word is broken down phonetically, so you are not only learning how to say the words, you are learning how to read and write portuguese as well. I am having great success at the new language and look forward to starting another from this series.
