After I've sent my revised draft to my agent and editor, they suggest more improvement sand again, this revision phase can take anywhere from a few hours to a few months.
Sometimes I can spend as long revising a manuscript as I spent writing it in the first place.
The deadlines are much, much longer with books. When I was a reporter, a lot of times I'd come in at 8:30 a.m., get an assignment right away, interview somebody, turn the story in by 9:30, and have the finished story in the paper that landed on my desk by noon.
