Hey! Do you like J.K. Rowling books?
I have never read ANY of her books even though they have won multiple awards and sold more than 400 million copies!  Have you?
I haven't either but I have heard a lot of people talking about them. Isn't that the author of the Harry Potter series?
Yes!  Harry Potter is a series of fantasy novels JK Rowling has written.  I don't know much about them, though
I have a lot of friends who are big Harry Potter fans. Do you know how many books were in the series?
I have no idea - but I know they chronicle the life of a young wizard, Harry Potter and his friends Hermione Granger and Ron Weasley, who are all students at Hogwarts School of Witchcraft and Wizardry. 
Very interesting! Do you know when the books were written?
On June 26, 1997 the Harry Potter and the Philosopher's Stone was released. 
Ah okay, does she still write books other than Harry Potter?
yes she's written 4 books for adults Casual Vacancy, The Cuckoos Calling, Silkworm and Career of Evil.  I've never read any of them!
