One problem with literature in High School is that the novels are looked at as nothing more than HURDLES you have to jump in order to pass the exams asking questions about them. It's tough to just sit back and enjoy a novel when you know your grade depends on it.
My favorite contemporary type
novels are "Winter's Tale" by Mark Helprin and "Huckleberry Finn." I don't see how anyone can go through life without reading both...
My favorite literary work of all time on all levels is LOTR by Tolkien, which I read once every c. 10 years.
I Read "Go to the Widowmaker" in college (30+ years ago) and loved it, have not read Jones since, though.
Know that Hemingway is vulnerable to criticism, but love him anyway, his writing had a quality, that while perhaps easy to satirize, has never been duplicated.
