More about the book

Can we change the past? Should we alter history? This novel explores the science, paradoxes, and philosophy of time travel and the opportunities and dangers of changing the past. With strong, engaging characters and plausible futuristic science, you will be caught up in the drama of people facing the choice of trying to save the world at the expense of their own loves, lives, and times. A terrible nuclear war has devastated the Earth but it recovers. Then a scientist discovers that the disaster hinged on one man's decision: a decision he has the power to change. He could save a billion lives -- if he is willing to destroy his own world. He succeeds and the world moves on. But saving the world from one war plants the seeds for a worse disaster to follow, and civilization falls. By the time our distant descendants rediscover the world of science, they find an even greater catastrophe is coming for them from the skies. They cannot change it or escape it, but in humanity's last great effort, they send one man back to the distant past to buy the world more time. Yet even that is not enough, and though civilization recovers faster this time, again the world faces annihilation... and a new generation must race to discover the final key.
