Animal Farm: I had a good experience reading this book. It may be short, but, as a allegory, it’s quite packed with details.
The Awakening: While I adored Chopin’s novel, the rest of my class hated it. If you’re interested in feminism and are looking for an intimate narrative (at least, I felt quite close to Edna as I read the book), then this would be an excellent choice.
The Great Gatsby: I liked Gatsby, but not as much as my fellow English majors. However, it is an important, canonized novel and there is a ton of information out there not only to help shape your research, but also to help you contextualize the time period and identify the autobiographical components in relation to Fitzgerald.
Heart of Darkness: Admittedly, I was not a fan. It was too dense and made me feel suffocated.
Of Mice and Men: It’s not a bad story, but I am not a fan of Steinbeck’s writing style.
Slaughterhouse Five: Absolutely love this one and since I am taking a class on 9/11 literature, the parallels interest me. I might even write a research paper on it myself. Vonnegut’s prose is pretty delicious, too.
The Things They Carried: I wrote a paper that I might present on O’Brien’s collection last quarter for my graduate course. There is a lot to work with in this, especially if you are either interested in postcolonial or trauma theory. It can get a bit gory, though.
To Kill a Mockingbird: While I thoroughly enjoyed Lee’s novel, I don’t know that I have much to say about it from a literary perspective. Maybe it’s been too long since I read it, though.
The rest I haven’t read yet and cannot comment on.
TL;DR: I personally would choose The Awakening, Slaughterhouse Five, or The Things They Carried, but that is because the style, themes, topics, and characters are the ones that catch my interest the most.
