But now the story is saying to me, "You could make a novel out of this." Yeah. Maybe for NaNoWriMo, not sooner.
I believe I will begin writing it tomorrow night, as I don't want to get so wrapped up in the worldbuilding and the cult my protagonist belongs to that I ignore the real point of the story.
I have also bought a copy of Strange Little Girls, which is a previous anthology that Sirens Call published recently. I want to get a feel for the kinds of stories and settings that they are looking for.
