For a lot of Harry Potter fans, J.K. Rowling's words have helped in hard times. Still, I can't begin to imagine what Cassidy Stay has suffered.
The 15-year-old survived the shooting that left her whole family dead, but found hope in Albus Dumbledore, whom she quoted at their memorial service.
J.K. Rowling heard about Cassidy's tragedy - and her undying love of Harry Potter - and responded in the kindest way.
She wrote Cassidy Stay a handwritten acceptance letter to Hogwarts (in Dumbledore's signature purple ink), including a wand and an autographed copy of Harry Potter and the Prisoner of Azkaban.
Nothing can bring Cassidy's family back, but J.K. Rowling's letter has shown that magic remains. This simple act of kindness will not be forgotten.
