Top Dog: A Rough Romance (Mercenary Masters Book 3)

She was used to doing things her way. Then he took her over his knee.

When beautiful, headstrong medic Rhiannon Farrell disobeys her commanding officer and undertakes a dangerous mission on her own, she ends up over black ops soldier Sawyer Barnes’ knee for a painful spanking followed by an even more shameful demonstration of his dominance. But as humiliating as it is to be bared and punished like a naughty little girl, her body’s response to the infuriatingly sexy brute cannot be denied, and it isn’t long before she is calling him master.

As Sawyer introduces her to a world of stern authority and blushing surrender, every quivering climax makes it more clear that she belongs to him, but when Rhiannon is captured and held prisoner by a ruthless enemy will the ordeal change the nature of their relationship forever?
