Most books about time travel follow the same rules. If you change something in the past, the future is rewritten. Sometimes for the better but usually for the worse. Tom Barren lives in 2016 where technology is king, there is no war, cars fly and life is good overall. Tom gets caught up in a time travel accident and the new 2016 is good for him personally though everyone thinks he’s John Barren, even if the tech is more like the world we know. So should he go back and change it back to where it should be and risk losing everything or if he tries, how much worse can it be?
The author does a good job of building the worlds in the timelines. You also start wondering, is there a timeline crossover or is one reality a delusion of another one? Are there more timelines? As things change will past mistakes be corrected or will they be worse?
I had a little trouble with the ending, seemed to be rather more sophisticated than it had to be but it was still very good.
