Perhaps it refers to the process of winter, like the changing of the seasons, the way nature behaves during winter, being depicted in a graphic novel. It could show how animals adapt, how people's lives change in a wintery setting, with illustrations and panels that bring this winter - based story to life. The graphic novel might use different art styles to capture the essence of winter, from the icy blues of a frozen lake to the warm oranges of a fireplace inside a cozy home.
I'm not sure specifically as it's not a well - known common title. It could potentially be about a story set in winter that is being transformed into a graphic novel. Maybe it's about how the cold, snowy winter landscape and the events that occur during winter are being adapted into a visual, sequential art form.
Well, without more context, it's difficult to say precisely. 'Winter turning a graphic novel' might be about a personal project where someone is taking their experiences or a story related to winter and making it into a graphic novel. It could involve characters dealing with the challenges of winter, like cold weather, isolation, or holiday - related events, all presented in the format of a graphic novel.
