Maya Radelis struggles with the guilt of her sister's death and the stress of her medical residency. When she runs away to Scotland to take a break from her troubles, she finds her way to an antique shop and a century-old engagement ring. But it seems it is more than a coincidence that the ring has been waiting for Maya to find it. It reveals the story of Rebecca Miller, a physician who wore it during the World War I. With the help of a fellow New Yorker, David Fischer, Maya follows the memories stored in the ring around Europe as she learns about Rebecca's life. As she discovers Rebecca's story, will Maya perhaps change her own?
