Novatopia is a book I started writing few years ago. It is a story about a time traveller, who ends up in a kind of perfect world and is trying to adjust there. It is also about how human being can develop a peaceful society, full of love.
The basic idea is that they started uniting and dropping their egoisms after scientists find out that our sun will become a nova much sooner than everybody thought up to then. They joined forces and developed space travel and started searching for a new home together.
