This novel was written by Maria Lodi and is titled Charlotte Morel: The Siege. It was translated from French to English by Anne Carter and published by G.P. Putnam's Sons, New York.
It is in very good condition, with a dust jacket that has some light wear and an inch-long tear in the back, along with a few other tears around the outer jacket.
The pages are clean and this 1970 book would make a wonderful addition to a collection of vintage novels.
