An improbable call for help from River Song draws the Doctor and Amy to the wreck of the starship Byzantium on the world of Alfava Metraxis. The wreck contains a deadly cargo – a Weeping Angel, determined to escape. And the starship’s crash site, infringing on a sprawling subterranean tomb, is no coincidence.

In uneasy alliance with a squad of military clerics, the Doctor’s investigation becomes a desperate battle to survive as an army of implacable, quantum-locked killers grows ever stronger – and flesh becomes stone.
