Chisulo Nkosi wanted Kam Okonkwo from the day she accepted the project to design the museum that would house the priceless artifacts he'd both collected and oversaw for his family's estate. Unfortunately for Chisulo, the lovely architect was off limits. For centuries, the Nkosi and Okonkwo fought for dominance among the clans of shifters in which they reigned supreme. Now, a new conflict stands before them. It's rumored that the Okonkwo are developing a serum that can suppress or in some cases obliterate the shifting phenomena. Only one final addition to the formula and the serum will be complete. The addition rests within Kam-the one person who does not possess the shifting ability. The Nkosi believe that if they can get to Kam, they could be first to create the serum. Chisulo is at first unaware of his family's true motives. His only intention is to have Kam surrender to him body and soul. She vows to never swoon before the towering dark male whose smoldering midnight looks and blatant sex appeal mesmerize any woman he meets. The silent challenge posed between them only throws into overdrive Chisulo's determination to have her. But secrets await that will instill hatred over love, vengeance over desire. Secrets, that include the murder of Kam's brother by one of the Nkosi and the acquisition of the serum-which Kam's blood must be spilled in order to create.
