The Aurora Borealis spacecraft has been on its way to the planet Gemina - Earth's twin sister - for over a hundred years. Rosalita, a seventeen-year-old from the Republic of Terra, leads an ordinary, boring life until fate presents her with an irresistible opportunity: by winning a scholarship in the sumptuous Golden Republic, a young Terran woman gets a chance for a better fortune.

The beginning is not easy, but when everything starts to fall into place, what is soon to come will change her life 180 degrees.

How do you stay yourself when the whole known world turns to dust and many seemingly trivial events have a second bottom? And how to recognize who is friend and who is enemy?

Rosa learns first-hand that nothing is given to us once and for all, and the unimaginable sometimes comes.
