Mary DiNunzio is strong, smart and has plenty of attitude. She’s become a big-time business-getter at Rosato & Associates, but the last person she expects to walk into her office one morning - in six inch stilettos - is super-sexy Trish Gambone, her old high school rival. Trish was the head Mean Girl who flunked religion and excelled at smoking in the bathroom.

Trish’s life has taken a horrifying turn. She’s terrified of her live-in boyfriend who is an abusing, gun-toting drug dealer for the South Philly mob. Mary remembers the guy from high school too - she had a major crush on him. Before Mary knows it, Trish vanishes. A dead body turns up in an alley, and Mary is plunged into a nightmare - that threatens her family, her job and even her life.

Mary goes on a one-woman crusade to unmask the killer, and finds love in a very unexpected place. Along the way, she’s forced to confront some very uncomfortable truths about her past and the profound effects of lifelong love - and hate.
