The line between right and wrong had always been clear to FBI Agent Nikita Valance. As far as she was concerned, there was no in between. But that would all change with her latest assignment, as she was about to live and breathe in the grey area. Infiltrating the Calaway firm was never going to be an easy task, but it's made even harder when she finds that there is more to the lives of those on the wrong side of the law, than what she initially considered. As she grows closer to the fierce and sexy Dashiel Calaway, she begins to feel things towards all of them that she never thought she would and starts taking more and more risks to help and protect those that she's sworn to arrest. Little does she know that the biggest battle is yet to come, as she has to face the choice between her head and her heart. A choice that comes with irreversible consequences when she crosses her professional line in a way that will be impossible to come back from, covering for those that she's now living with, and making herself a target too.
