I have recently reached the 75,000 word mark in my manuscript and have had many a friend and family member badger me to get it published--or at least try. And I wish to, it is my dream to become an author (as cliched as that is) However, my work's first draft originated as a short 45,000 word fanfiction I posted online. I've edited it, added to it, cleaned and polished it to a 76,000 word and counting story of my own creation, but I fear the sending it off due to not knowing if a) I should tell the publishers/agents in my submittion. B) If it will be overlooked because of its history Or c) if any of this is legal. I've made the mistake of falling in love with the characters and story of this book. They are like my children and the world is my own. I don't want to abandon it. I've changed a fanfiction about a lovecraftian radio station into a steampunk, demon hunting fantasy and I have no idea what to do about it. What should I do?
