What does someone do if their work tends to be adult yet not? By this I mean tonally speaking it is closer to adult fiction, though the voice of the main character's suggests middle grade? I'm thinking of taking another stab at Nymphs Of Winter Fire in a revision (maybe included the dis guarded subplot that would take it to twenty seven thousand words), as while it's technically middle grade, the tone is much darker than what I'm used to currently writing. It's dark, but it's not as dark as it could be. Yet much darker than my current short short fiction.
Edit: I decided to change the title. The title makes all the difference in confusion or not.
