There are hundreds of great and enriching novelists in the world's literature of which I have read probably less than 1%. My two favourites, from what I have read, are Pramoedya Ananta Toer from Indonesia and Howard Fast from the United States. Pramoedya's four volume series: THIS EARTH OF MANKIND, CHILD OF ALL NATIONS, FOOTSTEPS and HOUSE OF GLASS are my favourite Pramoedya novels. SPARTACUS and CITIZEN TOM PAINE are my favourite Fast novels.
Here are two links to websites about these authors: Pramoedya Ananta Toer and Howard Fast.
Please let me know if there are better websites on these authors.
