Alastair Reynolds is back with an eerie mix of fantasy and science fiction, in a riveting novella that combines golden age adventure with the sophisticated sensibilities of Station Eleven. In a deep medieval future, a band of players travels across France to perform the same old tales in the same old towns. When passing soldiers entrust them with a mysterious box that they say must be delivered to the Imperator, old playwright Master Guillaume and young escaped thief Rufus puzzle at what the box might contain. When Rufus overhears strange conversations between his Master Guillaume and the thing in the box, he must choose between his loyalty to the man who saved him from the noose and fear of the ancient intelligence working in their midst. Secrets spill out over the road to Avignon, and none in the troupe are safe. Not Blind Benedict, who once saw the faceless Empty Knight patrolling the deathless Wald that creeps ever closer to the cities, and not Master Bernard whose sensible plans are not equal to the eldritch thing the company now carries with them. All the world's a stage, and so was every world that came before.
