From the New York Times bestselling author of Roses comes a gripping new novel about five young spies embedded among the highest Nazi ranks in occupied Paris

At the height of World War II, a handful of idealistic young Americans receive a mysterious letter from the government, asking them if they are willing to fight for their country. The men and women from very different backgrounds-a Texan athlete with German roots, an upper-crust son of a French mother and a wealthy businessman, a dirt-poor Midwestern fly fisherman, an orphaned fashion designer, and a ravishingly beautiful female fencer-all answer the call of duty, but each for a secret reason of her or his own. They bond immediately, in a group code-named Dragonfly.

Thus begins a dramatic cat-and-mouse game, as the group seeks to stay under the radar until a fatal misstep leads to the capture and the firing-squad execution of one of their team. But...is everything as it seems, or is this one more elaborate act of spycraft?
