JK Rowling has written to a teenage girl who was the sole survivor of mass shooting that left her entire family dead.
Cassidy Stay's mother, father, two younger sisters and two younger brothers were all murdered by a gunman at their home in Texas, America in July.
But the 15-year-old survived the attack by pretending to be dead after suffering gunshot wounds to her head and hand.
During a memorial just three days after the shootings, the teenager quoted the fictional headmaster in Harry Potter, Albus Dumbledore, in a moving speech.
She told mourners: "In The Prisoner Of Azkaban, Dumbledore says, 'Happiness can be found even in the darkest times if one only remembers to turn on the light'.
"I know that my mom, dad, Bryan, Emily, Becca, and Zach are in a much better place and that I'll be able to see them again one day. Stay strong."
Cassidy's tragic story prompted the start of a Facebook campaign titled "We want JK Rowling to Meet Cassidy Stay", which has so far been liked by more than 4,000 people.
After hearing of her harrowing ordeal, the Harry Potter author made contact with Cassidy, sending her a handwritten note accompanied with a wand, a Hogwart's acceptance letter, a list of school supplies and a signed book.
A spokesperson for the author confirmed that Rowling was in touch with the 15-year-old, but said the contents of the letter would remain private.
"We can confirm that JK Rowling was in touch with Cassidy Stay, however, the contents of the letter remain private."
Asked whether a meeting between the two may happen, the spokesperson added: "We wouldn't comment on that but [Cassidy's] is a remarkable story."
A fundraising campaign for Cassidy has so far raised nearly $400,000, with the proceeds expected to help provide the teenager with financial support in the absence of her family.
Ronald Lee Haskell has been charged with the murders in what has been described as a "domestic dispute".
Prosecutors claim the 33-year-old tied the family up before shooting them in the back of the head, after demanding answers as to the whereabouts of his ex-wife.
