The Lady's Guide to Celestial Mechanics

The day Lucy Muchelney's lover marries another is the day she realizes her life as she knew it is over. Her lover marries a man to collect an inheritance, her brother plans to sell her telescope to fund his artistic endeavors, and with her father dead, her ties to the scientific community are crumbling away. Then she receives a letter addressed to her father from the widowed Catherine St. Day, the Countess of Moth, asking his recommendation for an interpreter to translate a revolutionary work of astronomy, and she seizes her chance. When Lucy shows up at Catherine's home, the Countess isn't sure what to make of her. Her claim to have done most of her father's mathematical equations is absurd, isn't it? The scientific society won't accept a woman as a translator, let alone as a mathematician or a member. But as Catherine realizes Lucy is the read deal, she also discovers Lucy may just be the greatest adventure she's ever undertaken…if society doesn't find out.
