Cause and Effect

moreOctober 1998, eighth year. Luna Lovegood picks up a paradox alarm, finds a phial on her desk she has no memory of brewing, and a note in her own careful hand. A few hours and one turn of the time-turner later she has to explain to Harry Potter why the last two years of his life were somebody else's work — and why the only honest potion in this story doesn't create love but simply reveals it. A light, talky comedy about a time loop in which everything has already happened: all that's left is not to get in its way.
