[AU, eventual George/Luna] Fred and George Weasley stumble upon a mysterious magical artifact: a pocket watch that predicts the time of death of the holder. Right now, that watch is saying that in four years, four months, and nineteen days, they are going to die. This leads them on an adventure that will test their bond and their sanity as they try to change their fate.

A missing scene from the Deathly Hallows epilogue. George and Percy send their children off on the Hogwarts Express.
