From the back of the book:
In the fantastic world of THE END OF ETERNITY this terrifying forecast was entirely possible. The Eternals, the ruling class of the Future, had the power of life and death not only over every human being but over the very centuries into which they were born. Past, Present, and Future could be created or destroyed at will.
You had to be special to become an Eternal. Andrew Harlan was special. Until he committed the one unforgivable sin-falling in love.
Eternals weren't supposed to have feelings. But Andrew Harlan could not deny the sensations that were struggling within him. Andrew knew he could not keep this secret forever. And so he began to plan his escape...a plan that changed his own past...and threatened Eternity itself.
This was a good read. I have always been interested in Time Travel, alternate realities, etc. This book explores those avenues. Imagine a society where Eternals have the ability to make changes in reality to make the world a better place. Is that a good thing?
