Hi Ale, Great that you are up for learning my language. To answer your questions a bit more information would be helpful. Do you need a language learning book and are looking for recommendations? Do you need a language learning book and are looking for someone who lives close to you so he or she can sell a used one? Or would you like to read a "normal" book written in German language? In all cases it would be good to know at what level your German knowledge is at this point. Total beginner or can you already communicate and read a bit/ quite well?
