Publisher's summary
Universe, meet its greatest assassin, Doom!

Plot
Doom's, the universe's surprisingly-chirpy "greatest assassin", sends out a video S.O.S.: someone allegedly sent "Death… literal Death" after her, and the entity is set to kill her within one day unless she can find the Doctor. Indeed, a mysterious shadow seems to be circling her even here. Every hour, her vortex manipulator can send her to new coordinates from a list of possible assignments supplied by the Lesser Order of Oberon. Finishing her spiel with a plea to tell the Doctor that "she's on her way" if the viewers of the message sees it, she activates her vortex manipulator and blasts off.
