Doctor Who - Ghost in the Machine (multi-era)
Ghost in the Machine by Rain. There's an explosion on the TARDIS and Rose gets turned into a time anomaly, bouncing back and forth through the Doctor's past(s). Multi-era, obviously, though from Rose's perspective, she's still traveling with the 9th Doctor. Read this one awhile ago, and liked it enough to ScrapBook it and save it into my bookmarks immediately (for all the good it's going to do, after I scrapbook a fic I really like, I go to the ScrapBook address on my computer that it was assigned, then I save that to my book marks, then I save my bookmarks to a jump drive so on the off chance the website the fic was on disappears into Cyber Space, I'll still have a copy on file). Only reason I didn't post it sooner was because I thought I already had.
