I'm writing a sci-fi novel set in the XXV century, during a fictional galactic war between two factions, which is part a spy-story and part the story of a journalist who has set out to document the war. I'm through with the spy-story part and I've just begun writing the journalist's part. I was wondering about how factual the journalist's story should be, or if I should bother adding a real-life touch to her story at all. I had no problem writing the first part, since I've played many games and watched plenty of spy-stories, but I'm having trouble getting started with the journalist's story, since I have but Hemingway's books and reportages to refer to. Some advice?
