From the back:

You don't meet women like these every day...

Marta Perry - had proven she could make her way in a man's world. She had beauty, social standing, money and power. As an ace divorce lawyer, she met the other things she craved - beautiful women.

Donna Bradshaw - was too young and attractive to remain the wife of an elderly tycoon. Marta trapped her - body and soul - into a game of thrills, dollars, and shattered lives.

Lynn Jordan - loved her husband, but allowed a quarrel to push her into Marta's different world.
