Like people who pass in and out of our lives, some books only stay with us for a short time, while others linger, inflecting our vocabulary with resonant phrases, or filling our heads with images, thoughts, and emotions. Those that linger typically alter our lives in some way — or at least, our outlooks on life. Poring back over the 30 books that changed our lives is a long-term project on the to-do list. But, to help you decide what book to pick up next, we devised a visual quiz that'll lead you to your next perfect read. Whether you're feeling angsty, glamorous, or like you just need to blow off some steam, this quiz will guide you to the book that will complement your current mood to a T — and maybe even change your life.
