Young adult fiction
Young adult literature (YA) is literature written for readers aged 12 to 18. It may include themes found in adult fiction, such as family dysfunction, substance abuse, alcoholism, and sexuality.
The earliest known use of term young adult occurred in 1942. Librarians developed the category of young adult literature to help bridge the gap between children's literature and adult literature. According to a study conducted in 2023, 55% of young adult literature consumers were over 18 years of age.
