Francine, The Lesbian Vampire

I'm writing a novel. It isn't exactly about a vampire, but there are fantasy elements. Francine is not human. Anymore. Francine is searching for the one, and she finds Masha. Masha and Francine are agents of justice. They can fly and they can appear as cats. They stalk and kill male predators, child molesters, and abusers of power. Francine looks like Michelle, and Masha looks like me. Eventually, Masha immaculately conceives the savior of the world, Christina. The book begins with Francine's suicide. It takes place in NYC, of course, and I have written three paragraphs so far. There is no reason why I can't write a novel! I am the most voracious and accomplished 30 year old reader that I know, I have a good imagination, and I only need to stick to it. I am nervous yet excited to write the "mating scenes," because the gothic gals have large, feathery black wings and they look like two bats in the act. The wings go away though, and they are able to walk/stalk the human world stealthily. I got this story idea while riding on the Septa train last weekend, driving through the depressing yet beautiful landscape of Northern Philadelphia and New Jersey. I was day dreaming about us as lesbian vampires living in a castle in Eastern Europe, but I have to fit the story to what I know. Until now, I always thought I can't write fiction, but I'm going to work really hard on this. If I can write a novel, I can make money and buy us a tiny piece of property in Brooklyn and Michelle will stop wanting to move.
