Young adult fiction
Young adult literature (YA) is typically written for readers aged 12 to 18 and includes most of the themes found in adult fiction, such as family dysfunction, substance abuse, alcoholism, and sexuality. It is characterized by simpler world building than adult literature as it seeks to highlight the experiences of adolescents in a variety of ways. There are various genres within young adult literature.
The earliest known use of term young adult occurred in 1942. Prior to the 1930s teenagers, adolescents and young adults were still considered children in society.
