Okay. I just want to tell you all this so you understand that even published authors get rejected.
I wrote a short story for an anthology that Evernight has put out calls for. It's something I've never written before called dark romance. I thought I understood it. I did not. LOL!! The story was rejected for the anthology, but I did receive a ton of notes from their acquisitions editors on revising it for a regular submission.
I will be expanding the story (the antho had a word count cap and it was hard for me to resolve the arcs within it anyway) and using what I've now learned about writing dark romance, and will be doing a series or two soon.
But yes, I got a rejection.
It happens to all of us, so keep your heads up and your fingers typing.
