Seduced by Sin

When Caleb Smith saved Francesca Hamilton from a nasty situation with her father, she was beyond grateful. Sure, it landed her in Caleb's bed wearing his engagement ring, but neither of them took that seriously. It was a means to an end, and he was so sexy and exciting, she was enjoying the ride. It wasn’t Caleb's fault her feelings were changing, leaving her wishing things between them were real rather than pretend.

Caleb took the FBI’s assignment because he wanted to end the tyranny of a man who’d hurt the people he loved. Odds of success were slim and the danger high, but he knew the risks. Francesca didn't and was completely in the dark about her family’s "business." And the more time he spends with her, the harder he falls for the gorgeous blonde. But to finally get retribution, he'll have to destroy her world...
