Doctor Who: Serpent Crest - Volume 1: Tsar Wars
In a distant galaxy, the Tsar and Tsarina rule over the Robotov Empire from the safety of their palace while human workers tend the power plants on satellite moons. When the Doctor arrives with Mrs Wibbsey, his identity is immediately mistaken, and the Tsarina believes that her old ally, Father Gregory, has returned. But when the Palace comes under attack, the Tsar suspects him of treachery.
Meanwhile, Mrs Wibbsey discovers that dark secrets are lurking in the shadows of one satellite moon. Far more than mere human rebellion is being planned, and Father Gregory is not operating alone. His actions will set off a chain of events with long-lasting consequences for the Doctor and Mrs Wibbsey.
