Below are just some of the questions JK Rowling answered in a 90 minute webchat.
SPOILER ALERT: Those who do not wish to know what happens to the characters after the book ends should stop reading here.
Rowling said the world was a sunnier, happier place after the seventh book and the death of Voldemort.
Harry Potter, who always voiced a desire to become an Auror, or someone who fights dark wizards, was named head of the Auror Department under the new wizarding government headed by his friend and ally, Kingsley Shacklebolt.
His wife, Ginny Weasley, stuck with her athletic career, playing for the Holyhead Harpies, the all-female Quidditch team. Eventually, Ginny left the team to raise their three children -- James, Albus and Lily -- while writing as the senior Quidditch correspondent for the wizarding newspaper, the Daily Prophet.
Harry's best friend Ron Weasley joined his brother, George, as a partner at their successful joke shop, Weasley's Wizard Wheezes. Hermione Granger, Ron's wife and the third person of the series' dark wizard fighting trio, furthered the rights of subjugated creatures, such as house elves, in the Department for the Regulation and Control of Magical Creatures before joining the magical law enforcement squad. The couple had two children -- Rose and Hugo.
Luna Lovegood, Harry's airily distracted friend with a love for imaginary animals who joins the fight against Voldemort in the Order of the Phoenix, becomes a famous wizarding naturalist who eventually marries the grandson of Newt Scamander, author of "Fantastic Beasts and Where to Find Them."
And what Muggle, or non-wizard, song would have been played at the funeral of Albus Dumbledore, the most brilliant and talented wizard the world had ever known?
"Surely 'I Did It My Way' by Frank Sinatra," Rowling told her fans, referring to the song "My Way," written by Paul Anka but popularized by Sinatra, among other singers.
