Articulating a conversation with my mom:
Literary fiction, if necessary, is happy to sacrifice plot for voice. In fact, if a writer is too focused on the character taking action for their goals, it’s considered gauche.
Speculative fiction, on the other hand, will sacrifice voice for plot. In fact, if a writer has their character sitting around thinking and feeling for too long, we get twitchy.
The best literature, across the board, successfully uses both skills, voice and plot, to create characters and tell an amazing story. But which sacrifice you are willing to make determines which conversation you are in.
