This hour of Modern Notion Daily, our guest Karen Abbott talks about her book, Liar, Temptress, Soldier, Spy: Four Women Undercover in the Civil War (Harper Perennial, paperback September 2015). Abbott explored the lives of four women who contributed to the war effort in unusual ways, from the Confederate spy who bedded countless Union soldiers to obtain secrets, to the woman who dressed as a man and enlisted in the Union Army. Later in the hour, Mark Hay explains the Kuiper Belt and why its so gosh darn cool.
