The Interviewer opens with a discussion of what he refers to as "'The Zombie War'" (1.1.1). This immediately breaks the unspoken commandment that thou shall not utter the word zombie in a zombie story.
This Zombie War has passed, and the Interviewer was tasked to write the United Nation's Postwar Commission Report on said conflict.
Unfortunately, once finished, he found half of his work trashed by the commission's chairperson.
The chairperson's reason: "'It was all too intimate'" with "'[t]oo many opinions, too many feelings'" (1.1.3). Well, duh. Who wants to read about people's feeling during the one of the most tragic events in fictional human history, anyway?
Based on the chairperson's snarky suggestion, the Interviewer decides to just write a book and do things his way.
Some might argue it's too soon to write such a book, what with China just declaring victory against the zombie hordes about ten years ago.
But the Interviewer believes it's his duty to get this information from those who lived though it while they remain un-dead and not, you know, undead.
The Interviewer concludes that he'll try to maintain an invisible a presence as possible during the proceedings. Instead, he'll let the human factor of those he's interviewing drive this book.
