Inspired by a true historical episode, Girl Waits with Gun, by Amy Stewart, starts with an automobile crashing into a buggy carrying the Kopp sisters. It’s 1914 in Paterson, New Jersey, and the villainous Henry Kaufman, drunken and erratic son of a rich factory owner, refuses to pay for the damages. He and his thugs soon begin a campaign of intimidation and escalating 
violence, testing the sisters’ courage. The eldest, the formidable Constance, will not give in, however, and soon finds that she is well suited to a life of action and adventure. A stolen baby and a long-buried family secret add to the exciting plot, and the rich characters and historical details will entertain and delight readers.
