Victoria Bristol is a young philanthropic socialite who is trying to move forward with her life after her mother's passing and continue her work with the local youth center and other charities. But when a fire breaks out during a charity gala, Victoria narrowly escapes a kidnapping attempt, and the only clue she has is a moth tattoo on her assailant's hand.

After spending six months in jail for a crime he didn't commit, Az Casadei is out for revenge against the woman who tried to bring him and his boys down. But as they position themselves as Victoria's bodyguards, they discover a puzzle of an alluring woman who may be far more dangerous than she seems. The attraction between Az and Victoria is undeniable, but their constant mistrust and personal war against each other makes things complicated.

As they work to unravel the mystery of who's trying to hurt her and frame the boys, the attraction between Victoria and the Horsemen grows hotter by the day. Can Victoria trust the Horsemen to protect her from harm, even as she finds herself falling for each one of them? And with danger lurking around every corner, will they be able to keep her safe?
