Ashtyn Carrier was 7 when she was diagnosed with a rare and almost unpronounceable immune-system disorder called hemophagocytic lymphohistiocytosis, better known as HLH. She and her family moved all the way from Minnesota so she could receive expert treatment at Cincinnati Children's. She received a successful bone-marrow transplant in August. In this "Tell Me a Story," Ashtyn and her dad talk about their experience leading up to the transplant.
