Mary DiNunzio is strong; she's smart; she's got plenty of attitude; and she's a big-time business-getter at Rosato & Associates. The last person she expects to walk into her office one morning is supersexy Trish Gambone, her high school rival.

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.

However, Trish's life has taken a horrifying turn. She's terrified of her abusive boyfriend. Unbeknownst to Trish, Mary had a major crush on him in high school, but now Trish vanishes, a dead body turns up in an alley, and Mary is plunged into a nightmare.
