For Parnelli "Nellie" Rafferty, the sexiest things in the world are women and automobiles. As a member of the "Carparazzi," she makes her living as an auto industry spy, trolling the proving grounds scattered throughout the world and snapping photos of the newest prototypes and models before the manufacturers officially unveil them to the public.

Jos Grant is just trying to get by. She stumbled into automotive espionage by accident, but when she realized how much she could make selling photos to magazines, and how thrilling it was to chase a Ferrari across Death Valley, she dumped her computer job. But membership in the Carparazzi comes with a price. Her partner has left her, and now she must juggle co-parenting her two children and the demands of her new career.

Until now, Nellie and the fast lane have always been a match made in heaven. But doing whatever is necessary to get the shot begins to lose its appeal when her attraction to her new, fiercest competitor begins to grow.

Then a French car manufacturer pits them against each other to keep a dangerous secret and Nellie must make the decision of her lifetime—are passion, love and loyalty worth giving up the chase?
