So I thought this might be another story about Rolex, but I wasn't certain. It's not though. If you're wondering about the red tie on the cover, it's because the rentboys refer to him as Red Tie. The driver, Callum, thinks his boss, James, might be self-medicating with the rentboys he sees. He'd much rather be the one his boss needs. But Cal is fairly certain those needs are special and seeks help from one of James's ex-rentboys, Nick, who is known for being a sexual sadist. 
 This story is told from Callum's point of view as he is learning to become a Dom and fulfill James's needs. Cal is believable as a new Dom, instinctive enough to make it work for James, but still insecure about reading his cues and getting it right, not losing control of himself in the scenes. These guys are private, so they're bedroom/home scenes, not dungeon scenes. 
 But what makes this story special is the navigation of their employer/employee relationship outside of sex. Because the sex is instinctual and natural between them. Figuring out how to act around each other the rest of the time is the hard part for James and Cal. By the end, you get the feeling that they'll manage to navigate the rocky patches and come out strong together. 
 Not my absolute favorite of the series, but a very strong addition to it. I love the rentboys, so I'm hoping there are more stories to come.
