To make it easier for me and my blog visitors, I am using the definition of the genres according to Goodreads.
CHILDREN’S – Children’s literature is for readers and listeners up to about age 12. It is often illustrated. The term is used in senses that sometimes exclude young-adult fiction, comic books, or other genres. Books specifically for children existed at least several hundred years ago.
YOUNG ADULT – Young-adult fiction (often abbreviated as YA) is fiction written for, published for, or marketed to adolescents and young adults, roughly ages 13 to 21.
NEW ADULT – New Adult fiction bridges the gap between Young Adult and Adult genres. It typically features protagonists between the ages of 18 and 26.
ADULT FICTION – Adult fiction, by contrast with children’s or young adult, is fiction intended for (and usually about) adults.
ASIAN LITERATURE – Asian literature is the literature produced by writers in Asia. Or by Asian American writers.
