Definitely. The novels are great because they allow you to use your imagination more than the visual medium of the TV show. You can picture the characters and the desolate landscapes in your own way. The storylines are engaging, full of suspense and unexpected twists. There are also some really interesting sub - plots that explore the relationships between the survivors in great detail, which makes for a very immersive reading experience.
The Walking dead novels are mostly regarded as canon. They contribute to the broader narrative and enrich the world-building. But like with many franchises, there can be differences in how different people view their canonicity.
The Walking Dead graphic novels are mainly black and white. Color versions are not the norm. The focus is more on the story and the art style in monochrome.
