Your answer doesn't necessarily need to be a book. It could be a paper, a study, someone else's thesis, anything. It could be a work of fiction as well. What someone is reading for entertainment can say a lot about a person. However, your response should be at a collegiate reading level or higher. If you decide to volunteer something more lighthearted, like a young adult or MG sci-fi/fantasy or romance novel, pair it with something else you may be reading that is more advanced. You could score extra points by advertising you read multiple books simultaneously with ease. If you are not currently reading anything because you're devoting your attention to other priorities, share something you've recently read that had an impact on you.
