Pattern Recognition is a novel set shortly after the events that took place in the United States on September 11, 2001. The book was published in 2005.
Cayce Pollard is a “coolhunter”, which means she has a gift for spotting the next cool trend. Big companies hire her to find that for them, and also to judge if their next logo is going to work for them or not. She leads a very solitary life, traveling from country to country for work.
In her spare time, she has become enamored with something called “The Footage”, which appears to be parts of a movie, snipped up, mixed up, and sent out onto the internet, somewhere, for people to find and comment on.
