I know this is more of a names site but I actually have a names. I do not have a good storyline. The main character's name will be Rosalie and she will be 11 or 12. Her older sister is named Skylar and she is 14. Skylar is really popular an likes fashion. She also has a younger sister named Isla who is 7 and is a tomboy who likes frogs. Rosalie will also have 2 friends that are side characters names Ellie and Peyton. I have been thinking about a good plot but i am totally stuck. I ant it to be something about sister conflict and in the end becoming closer together. I just don' know how to make it believable. Can you help me?
