"Para a Frente! 2nd Edition" by Larry D. King and Margarita Suñer
This is the perfect intermediate course in Portuguese, as a follow-up to "Brasil! Língua e cultura" or "Portugal: Língua e cultura," or any other first-year Portuguese text.
"Para a Frente!" first saw the light of day in 1981 when Larry D. King (University of North Carolina, Chapel Hill) and Margarita Suñer, (Cornell University) joined forces with publisher Tom Lathrop (University of Delaware, co-author of "Brasil!" and "Portugal: Língua e cultura), to produce one of, if not the most popular intermediate Portuguese book in the US. Now in its second edition after many reprintings, "Para a Frente! 2nd Edition" remains popular among students and teachers nationwide.
