I liked these MCs. The gruff FBI agent who is protecting his witness who can think on his feet. Had some nice sarcasm, sexy scenes and a nice little story with it. I wouldn't want to be Aaron's boss at work given how he pushes things and smarts off, but, he also gets the job done and that's what matters. Mark appears to be a really good balance to Aaron's personality. Want more about these guys as their relationship still developing when the novella ended.
