Unexpectedly reunited after six years, high school sweethearts Devin Shanahan and Grace Harrington cross paths and have a whirlwind wedding. A lot can change in six years, however, and they must figure out how to make their two independent lives mesh. Unable to disclose his CIA job to his new wife, when Devin is assigned a top-secret mission to Hong Kong, he tells Grace part of the truth: that he is going to work abroad for six months in finance. But when the mission turns deadly and Devin doesn't know whom to trust, he must make the most difficult decision of his life in an effort to keep Grace safe. Will the seeds of deception prove destructive to their newly formed marriage? And will the love that brought them together be the very thing their enemies use to tear them apart?
