London Word Festival Write about what you know. If you don’t know anything about anything, use an unreliable narrator or try science fiction. Write a lot. Set yourself a minimum target every day, and stick to it. One page a day is 365 pages a year. Five pages a day is a blockbuster in six months. When you submit your work, send three chapters and a synopsis, A4, one side of the paper, double spaced, with email backup, to an agent who represents authors who write books similar to yours.
