A completely new adventure based on the famous game from Bioware! A galaxy under siege. Every fifty thousand years, a race of living machines invades our galaxy in order to harvest all organic life forms. They are the Reapers. Two people who have learned the truth are desperately looking for a way to break the cycle: Fleet Admiral David Anderson and his girlfriend, Kali Sanders. They managed to find terrifying evidence that the Reapers are a real threat. But in doing so, they have entered the sphere of interests of Cerberus, a secret paramilitary organization, and its mysterious leader, the Illusive Man, who has put the lives of David and Kali at risk as he will stop at nothing to protect his secrets. Along the way, they meet a dubious but likely ally - Gillian Grayson, a girl with amazing abilities. Having once been the subject of Cerberus' horrifying scientific experiments, Gillian is now free and has learned to control her deadly powers, but upon learning that Cerberus is responsible for the death of her father, Gillian vows revenge on the organization and the Illusive Man, thereby jeopardizing the plans Kali and David and everything they stand for.
