The Crucifixion has been cancelled. The Aztecs and the Sioux are threatening nuclear war. The armies of Ancient Rome and Carthage have been destroyed by a force field. Human history is unraveling, and only a few people realize it is happening; the same team of music historians who faced an imploding universe a few years earlier. But this is different. The damage is being done by millions of people from the future, and they don't even know why it is happening. Who would do such a thing? The answers can only be found by taking a roller coaster ride through time where everything is constantly changing right before their eyes, and by enlisting the help of super A.I. from the distant future; machines millions of times more intelligent than humans. Can a handful of time traveling music experts muster these forces in time to save the Earth? The clock is ticking, and each second reduces their chances of success in a timeline so volatile that it can make people forget who they are and what they are doing just by being in it. The Second installment in The Timelines Series, it is another wild ride through time and technology with a random element nobody figured on: Who are those people in that Grand Cherokee and what are they up to?
