Marissa Kincaid is afraid of men - not men themselves, but the havoc that they can cause through unfaithfulness. Her father left her mother for another woman - twice - and Marissa's own dating history is littered with men who have cheated on her. Along with her friends Amy and Candi, Marissa sets up a website that dishes the dirt on men who cheat, and she supplies her own dating history as examples. Marissa includes Trent Jackson, her youthful love who cheated on her when she was aged 13, not realizing that it's going to start a war.

Trent is also working on publicizing a website, and when he finds out that he's been named and shamed by Marissa, he sets up his own website to report women who lie. Their mini-war of websites spills over into a radio show, until eventually they are challenged by the radio show to live together for five days and to see if they still hate each other by the end.

Trent and Marissa find, of course, that living with someone else means that you learn a lot more about them and begin to understand them. Trent's objectives in the radio competition are different from Marissa's, and he spends time trying to wear her down into having a relationship with him, although that will mean she forfeits the valuable prize. But Marissa's fear of cheating men is still significant, especially when she hears some more news from her family. Is Trent really worth giving up a million dollar prize?

This is a lighthearted book with some amusing characters and funny situations. There's little actual depth to it, even with regard to the concepts of women who are liars and men who are cheats. But it's a reasonable pastime for those who enjoy reading about feisty women and attractive, successful men.
