Advanced English Grammar In Use Martin Hewings -

4th Edition (with the updated ebook access). The 3rd Edition is fine if you find it cheap, but the 4th has clearer typography and refreshed examples. Sample takeaway from the book: “The difference between ‘I was reading when you called’ (background activity) and ‘I read the report yesterday’ (completed event) isn’t just time – it’s about foreground vs. background in narrative.” – Hewings explains this distinction across five units, not one. In short: The gold standard for advanced self-study grammar. Not a light read, but a rewarding one.
