The colonization of space beyond the limits of the Solar System became only a matter of time.

AUA

by Phillip Layton

In their world, they have no word for death. In our world, we have no word for AUA.

AUA is an exploration of the possibilities of life, and a celebration of the universe. It is more science fact than science fiction; its characters more like souls; its beginning starts with an ending, while at the end is the beginning of something completely different. My goal in AUA is to create a world where no-one is afraid anymore, and to find the core of what defines us. AUA is the notion that there are no walls but the ones we build ourselves, that there are no prisons except the one in which we are all incarcerated. I believe freedom lies in this book, your freedom, and I hope you find it....
