After losing her older brother, the Master, to a gunshot wound after The Year That Never Was, the Apocalypse is pushed back even further. But now that she has Jack back at her side and supporting her, she knows that she can push forward and keep going on. Donna Noble has been searching for the Apocalypse ever since she refused to travel with her after her wedding was crashed. Now that she's found her, the duo go off among the stars, but what's bugging the Apocalypse is that no one has ever run into her twice before. Now Donna has done it, and the last of the Time Lords is naturally suspicious. With Donna, Jack, and even Torchwood behind her, the Apocalypse is back and better than ever. But what happens when the mystery of the Medusa Cascade hits them, with all of reality at stake . . . and what happens when it's not just Rose that returns to aid her sister to the very end? Fourth in the Apocalypse Rising series. *** Doctor Who, Torchwood, and the Sarah Jane Adventures are owned by BBC, and anything recognizable from there, including characters and dialogue, belongs to them. However, the Apocalypse is my own OC, and she belongs to me.
