Kittenfish – [ˈkit-nˌfiSH] noun – a person using social media to create a false identity, especially to engage in deceptive online romances, but since she’s not a bad person and is only doing it because someone did something really bad to her and he deserves all this and more, then it’s kittenfishing. Barely fishing at all. Not reprehensible like catfishing but fully, defensibly, a court of law would uphold it, deserved by the guy getting kittenfished

When Marissa Ryan’s fiancé dumps her the night before her wedding, Marissa decides to get even. Not with her ex-fiancé—who’s obviously a hapless pawn—but with her greatest nemesis, Tarek Oliver. He’s the bane of her existence, the scourge of her city, the pee in the dating pool—and the very man who used both hands to shove her fiancé out of her life.
Marissa is determined that Tarek—the slick player who claims to have no feelings—will discover what it is to truly love and then suffer the blistering pain of loss. She’ll tear the love of Tarek’s life away from him just like he did to her. She just needs to create his true love first.
