Writers love their work, or they wouldn’t be writers. The problem is that writers also tend to love their characters and plot devices, even when those things don’t stand up to close (sometimes even casual) scrutiny. Reviewing a manuscript provides with the invaluable opportunity to put every aspect of your work to the sniff test, using common sense to check the believability of a plot device or a character’s behavior.
As the main story draws to a close, the writer faces the unenviable task of gathering up the loose ends of the plot and character arcs and tieing them neatly together. As your novel draws to a close, the reader wants to feel a sense of completion, like he’s not missing any parts of the story. The writer needs to identify plot hoots and character points, making sure that each of them is resolved. In a perfect novel, the two will work together to form a single inevitable conclusion.
Storytelling games such as computer and pen-and-paper role playing games (RPGs) rely on a story structure that funnels the characters along a single line of action. The characters must go to this inn, must speak to this barkeep, and must slay this dragon before the action can progress any farther. This tendency is occasionally disparagingly known as the “plot wagon”, or a means to get the characters from one plot point to another without diverging or chasing rabbit trails along the way. It makes for streamlined storytelling, but can seem very contrived if not handled correctly.
Conflict drives the action in your story and makes the reader care about your characters, their failures, and their triumphs. Your plot may be thought of as a tree. The characters are trying to reach the top of the tree. Conflict determines which branches they climb on the way to the top. Conflict in a story comes from two sources, internal and external.
