One True Thing by Amanda Grayson. ebook short. What an unsatisfying read! This m/m romance about an agent who has to go into deep cover by having his cover story planted in his brain was frustrating, particularly since it had so much potential. There was way too much story for a short, so the story had no depth and often seemed to jump around. And then the story just stopped, so you have no idea if they successfully completed the mission (i.e., the purported reason for the story).
