All novels have plots and characters. The question is: Where is the emphasis placed?
A plot-driven work is centered around the action. The characters in such a work rarely reflect on their deeds, their surroundings, etc. The characters are subordinate to the plot and don't have much time for reflection. Tom Clancy, for example.
A character-driven work focuses on the characters and how they develop throughout the story. Romance novels, Coming of age, etc. J.D. Salinger, for example.
Many works are a balance of both. It's what I'm striving for.
