A dubious distinction belongs to Mary Surratt: on July 7, 1865, she became the first woman to be executed by the United States government, accused of conspiring in the plot to assassinate not only President Abraham Lincoln, but also the vice president, the secretary of state, and General Grant.

Mary Surratt was a widow, a Catholic, a businesswoman, a slave owner, a Union resident, and the mother of a Confederate Secret Service courier. As the proprietor of the boardinghouse where John Wilkes Booth and his allies are known to have gathered, Mary Surratt was widely believed, as President Andrew Johnson famously put it, to have "kept the nest that hatched the egg." But did Mrs. Surratt truly commit treason by aiding and abetting Booth in his plot to murder the president? Or was she the victim of a spectacularly cruel coincidence? Here is YA nonfiction at its best--gripping, thought-provoking, and unputdownable.
