Genetopia is the story of a young man in search of his possibly abducted sister in a far future where nano- and biotechnology have transformed and accelerated the evolution of humans and their strangely altered surroundings. In this world, you can never take anything -- or anyone -- at face value. Illness and contact with the unknown are always to be feared, as viruses re-engineer genes and germ cells, migrating traits from species to species through plague and fever. Humankind lives in isolated communities, connected by trade routes, and always fighting to keep the unclean at arm's length.
But if Flint is to find his sister he must brave the fevers, the legendary beasts, the unknown. He must enter strange communities and seek help in the most unlikely places. He must confront both his own dark past and the future of his kind.
He must go into the wildlands.
Flint's story is the story of the last true humans, and of the struggles between those who want to defend their heritage and those who choose to embrace the new. But Flint doesn't see it like that: he just wants to find his sister.
