Grandma's Portal to Fortune

Poor farm woman Eleanor Shaw accidentally gains the ability to travel between two worlds. She sells ancient artifacts to the modern world to earn her first pot of gold, and brings modern affordable goods back to the ancient world to open a grocery store. Along the way, she overcomes the exclusion and schemes of her peers, expands her business on two fronts, eventually establishes a foothold in the modern world, and discovers that a blue-and-white vase holds a special secret.
