Read a lot. But read as a writer, to see how other writers are doing it. And make your knowledge of literature in English as deep and broad as you can. In workshops, writers are often told to read what is being written now, but if that is all you read, you are limiting yourself. You need to get a good overall sense of English literary history, so you can write out of that knowledge.
Theodora GossI'm used to writing fairy tales that can be somewhat dark, and the truth is that in fairy tales, romances are always problematic. They may end happily ever after, but someone's getting pushed into an oven or has blood in her shoe.
Theodora GossWhen we tell stories about things that are important - love, fear, beauty - we change the way people think about the world. Writers are, or should be, truth-tellers even when the stories themselves are fantasy.
