Dragonfly

"At the height of WWII, five idealistic young Americans receive a mysterious letter from the OSS, asking them if they are willing to fight for their country. The men and women from very different backgrounds . . . all answer the call of duty, but each for a secret reason of his or her own. They bond immediately, in a group code-named Dragonfly. Thus begins a . . . 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?"--OCLC.
