When someone makes a decision, no matter how significant or seemingly irrelevant, they cause unknown effects throughout history. Perhaps other, unreachable, factors are at play too. Does the universe have a destiny? Everywhere he looks, the Doctor sees the same patterns--the same events, decisions, and actions cropping up again and again. Look at the bigger picture, however, and maybe--just maybe--you'll see how the universe works. But, as the Doctor and his companions discover, are these patterns really there? Or do we, by the very nature of seeing them, define them? This new volume includes the winner of Big Finish's short-story competition.
