Helping a stranger can get you killed.

Tyton saves an unmarked Alliance ship from Reapers. Despite everyone else's warnings, Tyton decides to bring the rescued ship aboard the Wraith.

He's immediately sorry that he did. But the stranger knows things about each of the crew that could fill in the missing holes of their memories. He even knows the Wraith's mission.

But can they trust him?

Probably not, but Tyton is tired of flying blind, so they follow the stranger to Angkor dera. A world populated by criminals and outcasts-and the Covenant, a powerful religious order blessed by the god Satis Rai himself.

Tyton thinks the Covenant might have what the stranger is searching for. Perhaps... but the Covenant is also hiding something else. Something evil. Waiting for Tyton and his friends.

Waiting to infect the entire galaxy.
