Radish
The Commanders Club by Rowan Prose Publishing
Courtney Fox is a journalist on a mission—to save her protégé who's been conned into joining The Commander's Club, a white slave ring. FBI agent Ty Dragon is working undercover as a slave trainer. In real life, he prefers his females spanked, obedient, and hot, although he'd long ago given up on finding the right submissive mate. While setting up the Club's implosion, he teaches feisty Courtney the power of submission, and realizes the perfect woman might be right under his nose.
