Rowling was featured at the 2012 Summer Olympics opening ceremony in London where she read a few lines from J.M. Barrie's Peter Pan as part of a tribute to Great Ormond Street Hospital for Children. An inflatable representation of Lord Voldemort and other children's literary characters accompanied her reading.
Anticipating that the target audience of young boys might not want to read a book written by a woman, Rowling's publishers asked that she use two initials rather than her full name. As she had no middle name, she chose K (for "Kathleen", her grandmother's first name) as the second initial of her pen name.
