We want the horribly titled, "Tom Clancy's The Division: New York Collapse." It may have one of the worst names ever for a book, but it looks so damn good tying into the upcoming game with part of the same name. To figure out what really happened you'll have to skim through the extras the book comes with.
"...discarded survivalist field guide, written before the collapse, lies a
mystery—a handwritten account of a woman struggling to discover why New
York City fell."
