The blending trend of mixing and matching elements from different genres to tell a story is not limited to novels. Visual media are often the perfect way to tell a blended story, and while TV and movies get a lot of attention, comic book and graphic novels have been genre-blending for a long time.
The storytelling technique of comics really blends the best of the written and visual worlds, allowing the creators to (literally) illustrate scenes that a novelist can only describe. But you still get to keep some of that imaginative work that happens when you read novels – filling in the details in your head that are only inked on the page with soundtracks and special effects and how the character sounds in your head. It also is a format that allows you to proceed at your own pace, lingering over panels and pages that catch your fancy, whipping through scenes that somehow manage to convey movement and action through pen and ink.
