In recent years, Mary DiNunzio has become a big-time business-getter at Rosato & Associates, but the last person she expects to walk into her office one morning - in mile-high stilettos - is supersexy Trish Gambone, her high school rival. Back then, while Mary was becoming the straight-A president of the Latin Club and Most Likely to Achieve Sainthood, Trish was the head Mean Girl, who flunked religion and excelled at smoking in the bathroom. As it turns out, however, Trish's life has taken a horrifying turn. She's terrified of her live-in boyfriend, who's an abusive, gun-toting drug dealer for the South Philly mob. Only one problem - Mary remembers the guy from high school, too. Unbeknownst to Trish, Mary had a major crush on him. Before Mary knows it, Trish vanishes. Then a dead body turns up in an alley, and Mary is plunged into a nightmare, one that threatens her job, her family, and even her life. She goes on a one-woman crusade to unmask the killer, and on the way, finds new love in a very unexpected place, as well as discovering some pretty hard home truths about her past and herself.
