1928. For the people who live in New York City, Grand Central Terminal is a crown jewel, a masterpiece of design. For Clara Darden, the terminal is the stepping stone to her future. She is teaching at the lauded Grand Central School of Art, and dreams of creating cover art for Vogue. She's juggling the affections of two very different men-- with no idea they'll soon be blindsided by the looming Great Depression. In 1974 the terminal is full of grime and danger, from the smoke-blackened ceiling to the drug dealers who roam the floor. Recently divorced, Virginia Clay has accepted a job in the information booth to support herself and her daughter. Discovering an abandoned watercolor within the terminal, Virginia embarks on a quest to find the artist.
