Would love some easy German books for practice? Why just Spanish and Portuguese :-(
Search amazon for 'Wirton Arvel', lots of classic books with each paragraph in both English and German.
The book which helped me most was "Die kleine Hexe" (The Little Witch). It is a wonderful short childrens' book which is a joy to read and made me WANT to learn. It is available in English as well if you want to compare - but the German is quite easy
