Donna Noble is back home in London, catching up with her family and generally giving them all the gossip about her journeys. Her grandfather is especially overjoyed — he's discovered a new star and had it named after him. He takes the Doctor, as his special guest, to the naming ceremony. But the Doctor is suspicious about some of the other changes he can see in Earth's heavens. Particularly that bright star, right there. No not that one, that one, there, on the left...

The world's population is slowly being converted to a new path, a new way of thinking. Something is coming to Earth, an ancient force from the Dark Times. Something powerful, angry, and all-consuming...

At the heart of the ruined city of Arcopolis is the Fortress. It's a brutal structure placed here by one of the sides in a devastating intergalactic war that's long ended. Fifteen years ago, the entire population of the planet was killed in an instant by the weapon housed deep in the heart of the Fortress. Now only the ghosts remain.

The Doctor arrives, and determines to fight his way past the Fortress's automatic defences and put the weapon beyond use. But he soon discovers he's not the only person in Arcopolis. What is the true nature of the weapon? Is the planet really haunted? Who are the Eyeless? And what will happen if they get to the weapon before the Doctor?

The Doctor has a fight on his hands. And this time he's all on his own.

This is that story. It tells of Martha's travels from her arrival on Earth as the Toclafane attacked and decimated the population through to her return to Britain to face the Master. It tells how she spread the word and told people about the Doctor. The story of how she survived that terrible year.

But it's more than that. This is also a collection of the stories she tells — the stories of adventures she had with the Doctor that we haven't heard about before. The stories that inspired and saved the world...
