Raymond Murphy, English Grammar in Use with Answers: A Reference and Practice for Intermediate Students
This self-study reference book is clear and easy to understand. It is the type of book that you are always going to need and you can refer back to time and time again. An important aspect of this book is that it warns you what not to say and this clears all doubt in your mind about confusing alternatives. There are lots of exercises to practice which is great!
