"To read Rowling's novels as an adult is to sink into a half-remembered state of childhood rapture, the trance produced when you gobbled up fantasies for the first time. In the series's fourth volume, ''HARRY POTTER AND THE GOBLET OF FIRE,'' Dumbledore lets Harry stumble across the Pensieve, a collecting dish for excess memories. To extract a memory, a wizard holds a wand to his temple, draws a silvery strand of thought from his head and taps it into the basin. Any wizard who touches the swirling contents of the bowl drops into the visions it contains, reliving them as if he had been present at their inception. Dipping into the fiction that is Rowling's Pensieve, adult readers tumble into an eerie but familiar realm, containing not only Rowling's images of Harry but their own memories of books they loved when they were Harry's age and younger."Rowling, J. K. is the author of 'Harry Potter and the Half-Blood Prince ', published 2006 under ISBN 9780439785969 and ISBN 0439785960.
