This is a massive collection of 4 novels and 4 short stories about Inquisitor Gregor Eisenhorn set in the Warhammer 40,000 universe.
- “Regia Occulta”
- “Missing in Action”
- “Backcloth for a Crown Additional”
- “The Keeler Image”
- The Magos
I’ve never played Warhammer and this was my first encounter with the universe. The gist is that in the 41st century human scientific and social progress have ceased, humanity is united under a god-emperor, and humankind is fighting for survival against alien and occult forces.
It’s a pretty great setting, and these stories are a good read.
Of the novels, I thought The Magos was far and away the best. Although it is also the odd one out—the only story not told primarily from Eisenhorn’s first-person perspective. If you wanted to just dip your toe into this series to see if you like it, I would start with The Magos, and if you enjoy it, get the omnibus and start at the beginning. (Even though The Magos comes last in the timeline, I don’t think it spoils anything about the other stories.)
