Hannah Huth, right, smiles at customer Lisa Stepp as she purchases the 7-year-old’s books. Hannah has survived two brain tumors and written and illustrated two books about her experiences and how to overcome obstacles in life. She was at the Monroe Carell Jr. Children's Hospital at Vanderbilt last week to sign copies of her books, which are on sale in the Friends Shop for $10 each, with the proceeds going to VCH.
