There is this book, Ponto de Encontro, that is used to teach portuguese as a second language. It has great grammar practice. If you want something in portuguese, I think u can try a very well known grammar book in Brazil, GRAMATICA REFLEXIVA - William Roberto Cereja, Thereza Cochar Magalhães. Its actually a eight volume books used at schools (elementary/high school), so the language is very simple and objective, full of examples. A foreign friend of mine used those books to learn portuguese grammar and said they explain everything very well.

Para português europeu tem a série "Gramática ativa" http://www.lidel.pt/pt/catalogo/portugues-lingua-estrangeira/gramatica/gramatica-ativa-1-versao-portuguesa/

There is one that is for brazilian people studying for job public tender. I think this is a little difficult for foreign speakers, but in this kind of book you have contact with the most advanced grammar knowledge in details. http://lelivros.website/book/baixar-livro-a-gramatica-para-concursos-publicos-fernando-pestana-em-pdf-epub-e-mobi/
