Would you call Steven King's Carrie a YA novel simply because its protagonist is a teenager? No. Carrie is a horror novel, and despite the blurring of the lines drawn between children's literature, YA novels, and books intended for adults that has occurred since J.K. Rowling burst onto the scene, there is a difference. While no longer required to be almost as innocent and pure as children's literature YA novels tend to be more linear, straightforward, and simple than those for adults, as well as less graphic.
