When Samantha Rainford--new wife to Douglas Cosmo Rainford III--returns home from her honeymoon to find divorce papers waiting, she's shocked and heartbroken. Then she discovers that she's not the first to be abandoned--she's one of four (or maybe more) ex-Mrs. Rainfords--and decides it's time to put into practice that old truism: Don't get mad, get even.

With her knowledge from FBI training--which she may have flunked out of, but she remembers a thing or two--Sam gathers the other ex-Mrs. Rainfords to help her enact her revenge. Together, the motley crew attends a top-secret private special-ops training camp in the North Carolina mountains, where Sam meets fiercely disciplined ex-CIA operative Kollar Havapopulas.

Tall and as handsome as a Greek god, "Pappy" is the best at what he does--transforming civilians into highly skilled fighting teams. What he's less adept at, however, is telling a woman how he feels, and before long he discovers he's developing some very intense feelings for Samantha Rainford--an attraction that seems fated to be a total disaster. Two personalities as strong as Sam and Pappy are sure to strike sparks, but will the fire that burns between them consume everything in its path?
