One In A Quintillion

Ai has been plagued with hallucinations all her life and now she begrudgingly finds herself in therapy at her father's insistence. During a visitation from a phantasm in the form of her long dead mother she discovers she is living within a simulation which is just a single one in an ocean of simulations across existence. She needs to make a choice of whether to listen to those around her or follow her instinct to believe and fulfil the near impossible task required of her by the phantasm. Akash has a devastating diagnosis but due to his irreplaceable position in the plan to save the human race from an impending cataclysm, he is offered hope. While a cure for his condition is sought, Akash will be the keystone in creating an Artificial Intelligence enabled simulation that is to act as a lifeboat for humanity. Despite this Akash finds his very life at risk unless he can prove his worth. In attempting this so Akash begins on a path of adventure into the stars and back to Earth again where Akash and Ai finally meet. Together can they save the human race and learn the lessons needed to satisfy the final and ultimate task that Ai has been required to complete?
