Her position allows her access to information from almost every field. But, nothing, she says, prepared her for her son's diagnosis of an optic glioma. "It was a completely shocking and shattering experience, and it's taken many years to find a balance. Listening to families relate their own experiences for this book was immensely influential. I think it helped to bring things back full circle."
