An official tie-in to the hit video game Mass Effect: Andromeda. As the Quarian ark Keelah Si'yah sails toward the Andromeda galaxy, it carries 20,000 colonists from several races, including the Drell, Elcor, and Batarians. Along the way, a routine check reveals that many of the Drell colonists have died in their cryopods, and a pathogen is discovered. It begins to jump species, then the ship's tech begins to fail, making it clear that this is no accident. It's murder, and the perpetrator is still on board.

The ship's systems rapidly degrade, and panic spreads among the colonists. To make matters worse, the virus causes a terrible swelling of the brain that leads to madness, hallucinations, and violence. If the ship's crew cannot restore their technology and find a cure, the Keelah Si'yah will never make it to the Nexus.
