If we're gonna talk Great Texas Novel, then "What is Texas Literature?" The blog "A Practical Policy" which normally focuses on Liberation Lit and the Middle East, explored the topic in October of 2006. It begins:
"The question is sometimes asked, What is Texas literature? Is there one? And the answer is sometimes that Texas literature is more of a national literature than anything else – perhaps given that Texas has three of the 9 or 10 largest US cities and its vast countryside and great ethnic and class diversity and other factors. Among other Texas surprises, I suppose, there’s a book coming out on an “Asian underground railroad” that once ran through El Paso, Texas."
