Book 1 of the Paradise Series. - 3019: The world was now advanced in all sorts of technology. They were stronger than any species known. And now, they began their exploration of other planets, searching for what humanity wanted to find even during the past millennium: planets capable of hosting life and paradise to all. At last, in this very year, they have found a planet worthy of being Earth's twin. But as soon as the first humans landed on that same planet, they were killed, suggesting that they were not alone on the new planet. So NASA sent a group of humans to planet Greta to investigate. But eventually, they realized that there is more at stake than what they expected. -
