Shana Corey has written several picture books, among them Here Come the Girl Scouts!, a New York Times Editors’ Choice, and You Forgot Your Skirt, Amelia Bloomer, which the New York Times called “a picture book girls are likely to love.” She has always been intrigued by New York City history, so when she came across a passing mention of Alfred Ely Beach’s underground train, she wanted to know more. It wasn’t long before she was skulking around Warren and Murray Streets, looking for the site of Devlin’s department store, and seeking out Boss Tweed’s grave in Greenwood Cemetery.
