We are writing to you about our friend Gaby.  She is one of the kindest, sweetest girls we have ever met. But something's gone wrong. Gaby has a rare form of childhood cancer called Neuroblastoma. She is terminal. For us, this is heartbreaking. For Gaby, this is devastating. Gaby escapes into the worlds of Harry Potter and her greatest dream is to meet JK Rowling. We just want to see her smile, so please please sign and share the hashtag #JKmeetGaby
