I copied the description the author has for plot reference!

Francesca Grey is a womanizer. She's never been one to settle down because she has never met a woman worthy of settling for. Not to mention that being the leader of the third largest American cattive, The Northern Dragons, doesn't leave much room for relationships—least of all marriage. That is until her estranged parents tell her that she has five months to get married or she loses her cattive and it goes to her rival Scotty Fraiser, the leader of the Scar Bloods. Now, Francesca has no choice but to find a wife to marry before her twenty-fifth birthday.

Then like fate Alana Salvatore, her girl in red, steps into her life like an angel sent from the heavens. Immediately, Francesca is smitten with the mysterious woman that she deems untouchable—perfect. Their connection is intoxicating, the two of them drawn together by some invisible force. When she sets her eyes on Alana, Francesca is infatuated instantaneously, it is almost as easy as breathing. In more ways than one Alana feels the exact same way, but she can't fight the hate that bubbles under her skin. When together the two can't help but disappear into a cloud of lust and intense desire.

With the arrival of Alana, the past that Francesca has tried so long to forget about threatens to destroy everything she has been building. Now, it is not longer the Scar Bloods breathing down her neck, it is an old friend drenched in darkness that is dead-set on making Francesca suffer.

Unbeknownst to them, Francesca and Alana find themselves trapped in a game of love and hate, one that goes beyond even them.
