Miss Mary, Mack, Mack, Mack, all dressed in black, black, black..." We've all heard the clapping game song sung by children all over the world. But who exactly was Mary Mack and what are those silver buttons? Taking historical fiction to an all new level, Alexander G.J. takes you back in time to New York City in the early 19th century, to the world of Mary Elizabeth White, an eccentric, British-born, socialite who rubbed elbows with some of the most powerful families in the world. She was also a suffragette, opera singer, pianist, formidable fencer, and is rumored to have lived in a lighthouse on Fifth Avenue. When the RMS Lusitania is sunk by the Germans, it sets into motion a series of magical events connecting Mary's fate to the oncoming war, as well as a tragic accident at a circus in 1897 involving elephants and a little American girl, whose own world gets turned upside down. What is Mary's connection to the American girl and is she part of her father's tragic past?
