He needs to save his brother's big day—and may find love along the way . . . When special ops veteran Josh Robertson returns home to Nashville to be the best man at his younger brother's wedding, he's sure he'll mess it all up somehow. He's already on edge just from reuniting with his family after years in the service. It's fun to pick up his old guitar again—but facing his father is another story . . . But when it becomes clear the wedding might not go according to plan, it's up to Josh and fellow guest Louise Giles to make sure that the bride- and groom-to-be get their perfect day. Can Josh be the best man his brother needs? And is someone else beginning to realize that Josh could be her "best man" too?
