Brooklyn Aaron Davis is dead—again. When a nuclear war destroys humanity, Brooklyn (Brooks) travels back in time to save the world, a world that may not want to be saved. He has gone back to earth eight times already and, on each return, has failed to prevent the apocalypse. Meantime, The Window of Opportunity is closing fast. With one last chance to get it right, Brooks gambles on trying something completely different to save the world. But, unlike his previous efforts, if he fails this time, there is no do-over.
