I put together a list of the characters that I intend to use in this novel. In addition to the main character, I have a primary character, several secondary characters and the antagonist. What I will do over the next few weeks is develop their history and characterization.
I intend for this novel to be character-driven rather than plot-driven. My previous book was more about the plot. Unfortunately, I did not take the time to draw out the characters sufficiently. When I return to that novel I will take better care in learning about who those characters are. This time I want to concentrate more on the characters of this new project so that I have a better idea of who they are and how they will react to the events I will throw at them.
I have also written a paragraph that briefly describes the general plot of the story. When I begin pitching this novel I will need to refine this summary into more of a "high concept" description. However, I think I will wait on that until I have a better idea of the characters and their personalities. That way I can present a feel of the characters in the hook that I will use for querying.
