Keeping a consistent tone was one problem I wrestled with throughout the book. Consistency of tone is something that all fiction writers strive for.
Laurel Yourke defines tone as: "The expression of the author's attitute toward the subject, e.g. humorous, ironic, or satirical." See Take your Characters to Dinner (Lanham, MD: Univeristy Press of America, 2000, p. 203).When you write long fiction, you're going to be at it for a while before you come up with a draft. And during that time you do other things, think other thoughts, etc. You're never exactly the same person from day by day, even moment to moment. And each day you're going to write just a little differently. This will come out in your writing unless you focus on minimizing it. Short stories are not so challenging in this regard because there's enough time to get your mind around the story at each sitting.
