Novel trilogy There was a Great War 50 years ago. The world has just recovered and in a futuristic land of Galascia, the capital of the world, the government has created an artificial intelligence system called Erica. Aliens have been living among humans since before the Great War. The newest threat is that they pose a danger. Erica has been designed to eliminate this threat and although the aliens have evolved to look like humans, Erica can detect them looking at the sequences of DNA inside the beings. Aliens have different amino acids. However, what isn't known is that Erica's brain and memories were taken from a criminal. When Erica begins to malfunction she starts eliminating every politician and senior council member, a group of teenagers team up (both Android, alien and human) to travel back in time and prevent Erica from ever being built. However, they will encounter many challenges along the way and Erica is aware of their plans. "Time is the most undefinable yet paradoxical of things; the past is gone, the future is not come, and the present becomes the past even while we attempt to define it, and, like the flash of lightning, at once exists and expires." Charles Caleb Colton.
