It's the Epigraph!

"I don't know," she said. "I don't want to go through that hell again."

"We'd better keep away from each other."

"But, darling, I have to see you. It isn't all that you know."

Okay, so if I had to guess, I would say this novel is going to be about Brett and Jake and they journey to "find themselves" and "unveil their pasts." In my mind, the three lines at the top of this post say it all. Even though they do not go into detail about what "hell" they went through, due to their dialogue, the audience is now clued on in the fact that the two of them had a past with each other. Then, in the next two lines, we are shown that the two characters still have feelings for each other, despite the difficulties they endured in the past. Because of these lines of dialogue, the audience now has somewhat of a clue as to what this novel is going to be about. I am going to be honest that up until this point, I had no idea as to what was going to happen throughout the next 130 pages. But, thanks to Mr. Hemmingway, I now have a clue!
