 However, the writing of this book was interrupted for a few years when Martin returned to Hollywood to produce his TV series "Doorways" that ABC had ordered but ultimately never aired.In 1994, Martin gave his agent, Kirby McCauley, the first 200 pages and a two-page story projection as part of a planned trilogy with the novels "A Dance with Dragons" and "The Winds of Winter" intended to follow.When Martin had still not reached the novel's end at 1400 manuscript pages, he felt that the series needed to be four and eventually six books long, which he imagined as two linked trilogies of one long story.
