I have 2 ideas for 2 books. I cannot figure out which to write first. Can you help? Idea 1: "In Shadows" - This is based on the idea that Jack The Ripper took a boat into New York and continued killing there until he was caught and put in an asylum. It is not about Jack The Ripper, just a charecter based on him. Idea 2: "Black Rose" - A female singer named Rose Black is tired of dealing with her fame so she attempts suicide. She goes on to sell millions of records with her band and in the end realizes she actually died and everything since then was in her head as she is in Hell. So which sounds better?
