Mass Effect: Revelation (Vol. 1)

Humans have won the galaxy, but not the respect of the races they encountered in its expansion. When a research base on the planet Sidon is attacked and its occupants are brutally murdered, young Lieutenant David Anderson must quickly uncover the culprits. The answer to the mystery may lie with Kahlee Sanders, the base's sole survivor who has become a fugitive. Anderson must find Sanders before Saren, a ruthless turian Spectre, does so first, which could have dire consequences for humanity.
