The 2 word term that refers to books particularly aimed at young, female readers is "young adult" or "YA" books.
Young adult (YA) books are written and marketed for readers between the ages of 12 and 18, although many adults also enjoy reading them. These books often deal with issues that are relevant to young people, such as relationships, identity, social pressure, and self-discovery.
YA books can cover a wide range of genres, including romance, fantasy, science fiction, mystery, and contemporary fiction. They are typically written with a focus on character development and emotional resonance, and they often feature protagonists who are navigating the challenges of adolescence and coming of age.
In recent years, the popularity of YA books has skyrocketed, with many titles becoming international bestsellers and being adapted into movies and TV series. Some of the most well-known examples of YA books include "The Hunger Games," "The Fault in Our Stars," "Twilight," and "Harry Potter."
