During World War II in New York City, Dr. Kate Schulyer works at a hospital housed in a mansion. Kate knows that her mother, Lucy, lived at the property before she was married, when it was a boardinghouse--which the reader sees as Lucy's story is told. A third tale involves a woman named Olive and takes place in 1892, when the residence was the home of the wealthy Pratt family. How are the stories of Kate, Lucy, and Olive related? In The Forgotten Room, the trio of authors weave tales of secrets, love, and longing.
