To Catch a Cheat by Kelley St. John is loaded with sexual innuendo and low on plot. I really liked the concept. Marissa had a lot of cheaters in her life so she makes a website to out cheaters. The first guy she posts about is still around. He decides to launch his own site and makes the two of them into competitors. You'd have to read to see how the two are forced to be around each other.
And that's just it. They are forced to be around each other. All there is to focus on is their attraction. I liked some of the build up between the characters, but when the book was over I didn't feel like it was a keeper. The book seemed to need more. Reading the reviews at Amazon helped me see issues I probably would have just ignored otherwise, though.
If you choose to read, just beware. This book is more than just fluffy.
