This book, a work of fiction, is based on the true story of the Hungarian Gold Train, a train filled with confiscated wealth from thousands of Hungarian Jews, before they were sent to concentration camps. The train was captured from Austrians by American soldiers, shortly after the end of the war. The American Jewish soldier who is charged with protecting the contents of the train, takes one necklace for himself. Consumed with guilt, he gives it to his granddaughter Natalie shortly before his death and charges her with finding its rightful owners. Natalie subsequently enlists the help of a man, Amitai, who locates and buys stolen works of art. He then sells them and splits the money between the unlawful owners, the rightful heirs and his own company. He is in search of a famous painting. Natalie is in search of someone to give the necklace to. Their paths lead them not only to each other but to discovering what their purpose is in life. The second part of the book details the riveting story of the necklace, one that Natalie and Amitai will never know. I loved this book.
