West Point graduate Kenzie Wallis-Manning planned to make the Army her career, but after being severely wounded during her second deployment, and suffering from PTSD, she retires from the military and enrolls in law school. While studying in England, she receives a package containing an emerald brooch with a Gaelic inscription. As soon as she sounds out the words engraved on the stone, she is whisked back in time to May 28, 1944. When Elliott Fraser learns his friend's half-sister, Kenzie, has disappeared, he sends David McBain and Jack Mallory to the past to find her, and bring her and her soul mate back to the future. Will David discover the mission pits him against the best interests of Britain? Will Jack's penchant for getting in trouble put his life at risk again? Will Kenzie find her soul mate, or will she lose more on the battlefield of this war than she did in Afghanistan?
