What are popular young adult books?
Young adult novels typically tell a coming to age story with a main character in their teens or early adulthood.  From 2000-2015, common books for young adults are Harry Potter, Divergent, and The Hunger Games. Since them, young adult novels are more often showing themes of diversity, inclusion, and overcoming adversity and less focused on action-based storytelling. A popular graphic novel series, Heartstopper, is a good example of a popular book focused on DEI. This eventually turned into a high-profile television show on Netflix.
