Luna and Harry Head to the Ravenclaw Common Room

PAGES: 585-587

Harry and Luna leave the Room of Requirement under the Invisibility Cloak, sneaking through the castle toward the Ravenclaw common room. Along the way, Harry consults the Marauder's Map to avoid being caught by Filch or the Death Eaters patrolling the castle. They finally reach the Ravenclaw common room, where they encounter the knocker that asks a riddle before allowing entry.
