I frankly didn’t like it. I recommend Nabokov, though. Definitely read Frankenstein if you haven’t, The Great Gatsby, etc. It’s pretty much expected that you’ve read some of these books. I’ve heard T.C. Boyle is similar to Hemingway but a bit more sophisticated. Read Plato’s shorter works, like The Apology - great for someone interested in PoSci. You’ll definitely run into that, too. You can find it online, or in many book stores.

Also, you’ll probably run into MLK’s A Letter from Birmingham Jail:

Otherwise, just try to read books, think of possible theses/arguments, etc. It’ll help you with your major especially.
