An official tie-in towards the hit video game Mass Impact: Andromeda, written by award-winning and NY Instances bestselling author Catherynne M. Valente

The Quarian ark Keelah Si’yah sails toward the Andromeda galaxy, carrying 20,000 colonists from sundry races like the drell, the elcor, as well as the batarians. Thirty years off their destination, a regular check reveals drell laying dead within their pods, and a lethal pathogen up to speed. Soon, the condition is jumping species, and it quickly becomes clear that this is no incident. It’s murder, as well as the perpetrator continues to be on board.

The ship’s systems rapidly degrade, and panic spreads among the colonists, for the virus yields an awful swelling of the brain that causes madness, hallucinations, and dreadful violence. If the ship’s crew can’t restore their technology and find a cure, the Keelah Si’yah will never make it to the Nexus.
