Snatched out of the TARDIS in mid-teleport, Donna finds herself in an artificial world, where she meets the man of her dreams, has children, and enjoys a normal life with no sign of the Doctor or the TARDIS…until he suddenly appears in the place of her therapist, Dr. Moon, who she seems to see quite regularly. In the library, the Doctor’s attempts to detect his shadowy adversaries are being jammed by something, somewhere, and the ranks of the expedition are dwindling as more of its crew are consumed. Only the enigmatic Professor River Song can be of any real help to him, but the Doctor is still worried about how well she knows him – especially after she whispers one word to him that proves she knows him very well, and again when she proves that she’s more than willing to sacrifice her life to save him. Donna runs into a familiar face in the virtual construct, another victim of the Vashta Nerada who clues her in to the true nature of her new life, and she begins to question everything as her artificial world starts to collapse on itself. The Doctor realizes that Donna – and almost everyone else who was in the library before the shadows fell – have been saved in the Library’s massive computer core, but as the Vashta Nerada try to claim the library world and bring it to the brink of destruction, they may not leave him enough time to recover the survivors.
