"Nikki Griffin, a private-investigator when she isn't running her small bookstore, is on a case. The matriarch of one of the wealthiest San Francisco families has been defrauded by a con-man, and her furious son enlists Nikki to find the money. And find the con-man. Nikki isn't a fan of men who hurt women. Her secret mission, born of revenge and trauma, is to do everything she can to remove women from dangerous situations-and to punish the men responsible. As Nikki follows the trail toward the con-man, she realizes that no one involved is telling her the whole truth. When the case overlaps with her attempt to protect a woman in trouble, and Nikki's own life is put in danger, Nikki has to make terrible choices about who to save-and how to keep herself alive"--,Provided by publisher.
