Reviewing a new book on the teaching of Portuguese as a second language

I will soon receive the book ‘As variedades do português no ensino do português língua não materna’ edited by Christian Koch and Daniel Reimann  (Narr Francke Attempto) and review it for the LINGUIST List. The book is a collection of studies on the role of language varieties in the practice of teaching Portuguese as a second language. I can’t wait to receive my review copy and start reading the book!
