Donna Noble traveled with the Tenth Doctor, then was forced to forget everything about her time. But sometimes, at random times, she feels a strange sense of regret, like something is missing.

Set for the Doctor after Capaldi's. The Twelfth Doctor has just regenerated, leaving behind a new face, a new personality, and a universe to save and keep safe from aliens, astronauts, and archaeologists (they always get the facts wrong). This is the story of his adventures with Alexandria Estelle and the TARDIS.
