But Nikki is dating their brazen leader, and when the stakes become life-or-death, Cam is torn between following his heart and sacrificing everything to pay off his debts. In the vein of great box-office blockbusters, the high-stakes romance here sizzles within this page-turning thriller that will leave readers feeling like they are flying through the streets of New York.
