This genre may include modern fairy tales, which use fairy tale motifs in original plots, such as The Wonderful Wizard of Oz and The Hobbit, as well as erotic, violent, or otherwise more adult-oriented retellings of classic fairy tales (many of which, in many variants, were originally intended an audience of adults, or a mixed audience of all ages), such as the comic book series Fables. It can also include fairy tales with the plot fleshed out with characterization, setting, and fuller plots, to form a child's or young adult novel.
