The Exiled Jeweler by Susie Warren

There is a love/hate relationship between Emilia and Alex and it's seriously sexy:
                She whispered, “I’ve no desire to have a public relationship with you.”
                “You wish to keep it a private affair?”
                 He was playing with her and she needed to gain the upper hand.
                  “I don’t see how this could benefit you.”
                  He met her gaze. “Thirty seconds alone and I could demonstrate how I plan to benefit.”
I really liked this book, Alex was sexy and Emilia was a strong female.
