An Invitation to Portuguese by Margarita Madrigal [Leatherbound]

Total 220 pages. This is likely to be the best "Nature Method" equivalent for learning Portuguese over there. It is almost entirely in the target language and anyone who has a moderate knowledge of one of Germanic and Romance languages (e.g. English, French, German, Italian, etc.) will find no difficulty in reading and listening through the book.  The audio is available at our Patreon and Youtube pages.
