This is the first book in this series I have read, it is a stand alone book. Lennie and Natasha are reminiscing about their World War II days. Natasha is trying to write her memories from that time, with little success. This books is a love story, a mystery, a war story altied together. Very fast paced, sit on the edge of your chair book. Uvi Poznansky has a unique way of telling the story. I will get the first books and read them now. Highly recommend this book.
