Turnabout by D. M. Read

Twenty-four-year-old Nicholas Frayne is consumed by one idea—getting rich—until he meets Brooke Parnell, founder and CEO of Freedom Fashions. After he accepts the job of marketing specialist at her company, Nick embarks on the wildest ride of his life, never knowing what Brooke is going to do or say next. Little by little, Brooke chips away at Nick's preconceptions as to how women should look and behave. And even though his social media ads contribute to the company's success, Nick is afraid he'll never win Brooke's heart—until Freedom Fashions' biggest gamble of all turns the fashion world on its ears.
