Mass Effect Universe
Drew Karpyshyn, Catherynne M. Valente, Jason M. Hough, Karina Cooper, Mac Walters, N. K. Jemisin & William C. Dietz · 2 series · 7 novels · 2007–2018
Some ruins are too useful to question. Humanity found the mass relays already humming — roads between the stars laid by hands long gone — and stepped through into a galaxy that had been governed, feuded over, and quietly terrified for far longer than any newcomer was told. This is the Mass Effect universe: a crowded, treaty-bound Milky Way of turian fleets, asari diplomats, and Citadel Council politics, where the deadliest secret is not who holds the guns but what has wiped clean every advanced civilization that rose before this one. The galaxy was first charted as an interactive space opera, but the novels we hold run their own campaigns across it. Drew Karpyshyn — a lead writer of that spine — opens the shelf with a Milky Way trilogy, Revelation, Ascension, and Retribution, tracking humanity's black-ops Cerberus cell and its shadowy patron, the Illusive Man. A second wave crosses the void entirely: the Andromeda novels — Nexus Uprising, Initiation, Annihilation, by Jason M. Hough, Mac Walters, and Catherynne M. Valente — follow colonists who gamble everything on a fresh galaxy and arrive to find it already at war. The register is military hard-edged space opera with an undertow of extinction-scale dread: close-quarters intrigue and boarding actions up front, an apocalyptic clock ticking somewhere far out in dark space. Begin with Revelation, Karpyshyn's prequel to all of it — it introduces the soldier, the rogue agent, and the conspiracy the entire Milky Way arc turns on.
