(CONTAINS SPOILERS FOR HARRY POTTER AND THE ORDER OF THE PHOENIX)
Princess Luna and Luna Lovegood share little other than a name, until one day they both wake up in each other's places. Havoc and hilarity ensues as the unlikely pair try to figure out why and how they got there. Can the princess survive at Hogwarts? Will Luna drive everyone in Canterlot insane? Can the author write a satisfactory description? Well, probably not, but you should still read the story.
