Lucy McCarraher, author of Blood and Water, has posted the details of her writing process over on her blog.
She's very much one who plots in advance, with chapter breakdowns and the whole shebang, so if you're like me (that is, a bit vague most of the time) you'll want to read how she organizes it. Lucy's background is in television screenwriting, which, no matter how people snipe at TV, is a hyper-disciplined form with very specific parameters, like a sonnet.
Her method sounds like a great way to go, if you can get your mind to cooperate. (My flounder-ahead approach has the virtue of offering many surprises to the writer while writing; but many of those unexpected developments are surprises on the order of a flat tire.)
