The stunning conclusion to the first year of comic adventures with the Twelfth Doctor and Clara! The Doctor and Clara face impossible odds as the Hyperions - a race of sentient suns who scorched the universe until the Time Lords brought their reign of terror to an end - have returned, and, worse, have come to Earth, in an epic, four-part season finale! 

Plus - the pair face a marooned creature in a stately home, and visit San Diego Comic Con!
