The book Harry Potter and the Deathly Hallows is about Harry, Hermione, and Ron going on an adventure to find and destroy Voldermort's Horcruxes. A memorable quote that Fred said to George is: "Holey? You have the whole world of ear-related humor before you, you go for holey?"  One memorable quote Dumbledore said was: " Do not pity the dead, Harry. Pity the  living and, above all those who live without love."
