I was researching young adult literary genres, and I found this fun interactive and informative map. Click on the different areas to explore fiction, nonfiction, and YA fiction genres. It contains explanatory information for each genre and show examples from literature. For some of the wider genres, it also has subcategories.
To discover new genres or understand the definition of a genre a bit better go to Book Country to check out this map.
