What's your favorite genre of books?
I think for me it depends on the book, not the genre. Books can be categorized by genre, but they can't really be defined by it, so I can never be sure what I'll think about a book until I read it. However, the vast majority of what I read is YA fiction.
What's your favorite book?
Paper Towns, by John Green
Do you write in books?
Not usually. If the book matters a lot to me and I own it, then a lot of times I will underline my favorite quotes or dog-ear pages that mean a lot to me, but I don't usually annotate a ton unless it's for school.
