What to read after An Introductory Portuguese Grammar?

This book presents the elements of everyday Portuguese, stressing European Portuguese, but also giving information on Brazilian Portuguese. Covering grammatical topics, vocabulary, and practice sentence material, this book is a solid, well-organized approach to Portuguese that anyone interested in the language will find highly useful.
Pronunciation is very clearly explained first, and it is followed by twenty-five well-proportioned, progressive lessons that cover all the main points of contemporary grammar: gender, present indicative, formation of plural, agreement and position of adjectives, definite and indefinite article, use of ser and estar, commands, personal pronouns, imperfect indicative, reflexive pronouns and reflexive verbs, present subjunctive, future and imperfect subjunctive, conditional, negatives, infinitive, pluperfect and perfect indicative, and much more. An Appendix gives conjugations of regular verbs, orthographic-changing verbs, radical-changing verbs, and irregular verbs, while a Portuguese-English Vocabulary, an English-Portuguese Vocabulary, and an Index complete the book.
This book is suitable for self-study outside of class, for refresher, and for reference. It is particularly useful as a supplement to phrase and conversational study.
