My mother put me on to a most wonderful book. I will never part with it. "Fowlers Modern English Usage" It can be a bit pedantic, but if you love words (and English, as I do, in spite of what half the world says about it.) you will appreciate this one. Warning: not American.
Other books I picked up and find useful, almost any older secondary school grammar book from a second hand book shop. I won't suggest here, as you will need to find what ever is available to you. But do go back a few years.
A good dictionary, I use both an American (Websters) and two English (Oxford & Fowlers ), you can learn a lot and be inspired to write simply by studying the etymology of words.
Also reading good books that are well written, will give you an idea of how to write well. Some of Thomas Keneally's early books are stunningly written. (He of 'Shindlers List' fame, but NOT his best.) I am reading any Irish writer I can and going back to Steinbeck.
I have got carried away. You only asked for help to improve your English lit skills and here I am trying to make Shakespeare out of you. Sorry.
regards, huni. (and all the best.)
