Mass effect : retribution

Humanity has reached the stars, joining the vast galactic community of alien species. But beyond the fringes of explored space lurk the Reapers, a race of sentient starships bent on "harvesting" the galaxy's organic species for their own dark purpose. The Illusive Man, leader of the pro-human black ops group Cerberus, is one of the few who know the truth about the Reapers. To ensure humanity's survival, he launches a desperate plan to uncover the enemy's strengths--and weaknesses--by studying someone implanted with modified Reaper technology. He knows the perfect subject for his horrific experiments: former Cerberus operative Paul Grayson, who wrested his daughter from the cabal's control with the help of Ascension project director Kahlee Sanders. But when Kahlee learns that Grayson is missing, she turns to the only person she can trust: Alliance war hero Captain David Anderson. Together they set out to find the secret Cerberus facility where Grayson is being held. But they aren't the only ones after him. And time is running out. As the experiments continue, the sinister Reaper technology twists Grayson's mind. The insidious whispers grow ever stronger in his head, threatening to take over his very identity and unleash the Reapers on an unsuspecting galaxy. This novel is based on a Mature-rated video game. From the Paperback edition Every advanced society in the galaxy relies on the technology of the Protheans, an ancient species that vanished fifty thousand years ago. After discovering a cache of Prothean technology on Mars in 2148, humanity is spreading to the stars; the newest interstellar species, struggling to carve out its place in the greater galactic community. On the edge of colonized space, ship commander and Alliance war hero David Anderson investigates the remains of a top secret military research station; smoking ruins littered with bodies and unanswered questions. Who attacked this post and for what purpose? And where is Kahlee Sanders, the young scientist who mysteriously vanished from the base–hours before her colleagues were slaughtered? Sanders is now the prime suspect, but finding her creates more problems for Anderson than it solves. Partnered with a rogue alien agent he can’t trust and pursued by an assassin he can’t escape, Anderson battles impossible odds on uncharted worlds to uncover a sinister conspiracy . . . one he won’t live to tell about. Or so the enemy thinks.
