Astin Pharmaceutical and Biotech has its share of mad scientists. Delaine must get the goods on the crackpot who is using his scientific genius to create his own personal harem. During her investigation, she meets a man who would give Adonis a run for his money. After a messy divorce, Delaine is in no hurry to love anytime soon, but her spirit guide, a sleek, black mountain lion, is convinced he's their mate.

When Justin lays eyes on Delaine, he's dying to get next to her. There's one problem—he's seen her walking around a secret part of the Astin facility that she had no clearance to enter. Is she in league with the corrupt scientist he's tailing? Or is she a mole who could blow his case, or worse, his cover?

When Delaine discovers the man she's taken a chance on is undercover, a decision must be made. Should she kick his butt for not being honest about his undercover status while working her case? Or should she simply shoot him for sleeping with her best friend?
