She is an infamous killer. He is a principled rebel. Both have secrets. Both are hunted. Together they can alter the fate of the world. EARTH HAS FALLEN.         Surviving the end of the world is harder for nineteen-year-old Sky than most. Why? Because by a freak genetic accident she resembles the alien invaders. After years of committing atrocious deeds, she flees the lawless cities and finds refuge with a nomad community, hidden deep in the forest. Life is restful, peaceful until he arrives.         Ryan, a man who could be her twin, appears under the most mysterious circumstances. He claims to be a rebel from the East on a secret mission that could free Earth, but helping him comes with a price. They are hunting him and everyone near him becomes a target.         Forced together to stay alive, they evade vicious attacks and set out across gang-ruled and infected territories, to find her brother, Alex, a commander in the Liberator Army. As secrets unravel, Sky will discover Ryan is not the savior they imagined, but with the invaders closing in they must find a way to work together in order to save everyone.        A kickass, action-packed adventure in a future where survival is everything.                **Recommended for readers aged 15 years and above.                                        © 2021 by Mokbook.
