Yardley and KC discover what theyve been hiding from each other–that they are both agents, and theyve been keeping secrets from each other for years. It is clear their chemistry is anything but clandestine–even though their hearts are still broken by the weight of secrets built up through their relationship. But as they fly across oceans, race through windy European streets, and hide crammed together in sweaty closets, they not only have the chance to reclaim the mission, but come back to each other for good.
