Mass Effect

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?

It's humankind versus a race of machines bent on harvesting organic life in this second official novel based on the BioWare video game.

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.
