Young Adult

Young Adult. Young Adult (YA) books are written, published, and marketed to adolescents and young adults. The Young Adult Library Services Association (YALSA) defines a young adult as someone between the ages of 12 and 18, but adults also read these books. These are generally coming-of-age stories, and often cross into the fantasy and science fiction genres. YA novels feature diverse protagonists facing changes and challenges. This genre has become more popular with the success of novels like The Hunger Games, The Fault in Our Stars, and Twilight.
