Gossip Girl meets Succession in this steamy romance about a tenacious heiress who's planning big moves at her family's company, and her best friend's brother, a CEO hiding a secret that might be worth billions.

Off limits is up for negotiation...

Sloan Amari has spent years in the shadow of her carefree older brother Henry, heir to their family's company. Determined to prove that she's been the right choice for CEO all along, she's become a powerful corporate attorney in her own right and is on track to make history as the firm's youngest senior partner.

Enter her best friend's older brother, Marcus, who also happens to be Henry's closest friend. The two sets of siblings grew up together and became a tight foursome, until Marcus was pulled away from his life in Manhattan to lead his own company--one that rivals her family's. Now he's back after two years abroad, and Sloan feels the same electric attraction she's always felt for him. It's too easy to confide in him about her difficulties growing up biracial, and her desire to become the heir of Amari Global. Is this finally the moment they can act on their feelings? Or does Marcus have alternative reasons he returned to New York?
