Kings of Sin
Reading Order.

A diverse and steamy, forbidden billionaire romance from New York Times bestselling author and BookTok sensation Ana Huang! She's his opposite in every way...and the greatest temptation he's ever known. Reserved, controlled, and proper to a fault, Kai Young has neither the time nor inclination for chaos--and Isabella, with her purple hair and inappropriate jokes, is chaos personified. With a crucial CEO vote looming and a media empire at stake, the billionaire heir can't afford the distraction she brings. Isabella is everything he shouldn't want, but with every look and every touch, he's tempted to break all his rules...and claim her as his own. *** Bold, impulsive, and full of life, Isabella Valencia has never met a party she doesn't like or a man she couldn't charm...except for Kai Young. It shouldn't matter. He's not her type--the man translates classics into Latin for fun, and his membership at the exclusive club where she bartends means he's strictly off limits. But she can't deny that, beneath his cool exterior, is a man who could make her melt with just a touch. No matter how hard they try, they can't resist giving into their forbidden desires. Even if it costs them everything.

He had her, he lost her...and he'll do anything to win her back. Powerful, brilliant, and ambitious, Dominic Davenport clawed his way up from nothing to become the King of Wall Street. He has everything--a beautiful home, a beautiful wife, and more money than he could spend in a lifetime. But no matter how much he accumulates, he's never satisfied. In his endless quest for more, he drives away the only person who saw him as enough. It isn't until she's gone that he realizes there may be more to life than riches and glory...but by then, it may be too late. *** Kind, intelligent, and thoughtful, Alessandra Davenport has played the role of trophy wife for years. She stood by her husband while he built an empire, but now that they've reached the top, she realizes he's no longer the man she fell for. When it becomes clear that she'll always come second to his work, she finally takes charge of her life and puts herself first--even if it means leaving the only man she's ever loved. But what she didn't count on was his refusal to let her go...or for him to fight for their marriage, no matter what it takes.

He'd never wanted anyone enough to chase them...until he met her. Charming, easygoing, and rich beyond belief, Xavier Castillo has the world at his fingertips. He also has no interest in taking over his family's empire (much to his father's chagrin), but that hasn't stopped women from throwing themselves at him...unless the woman in question is his publicist. Nothing brings him more joy than riling her up, but when a tragedy forces them closer than ever, he must grapple with the uncertainty of his future--and the realization that the only person immune to his charms is the only one he truly wants. *** Cool, intelligent, and ambitious, Sloane Kensington is a high-powered publicist who's used to dealing with difficult clients. However, none infuriate--or tempt--her more than a certain billionaire heir, with his stupid dimples and laid-back attitude. She may be forced to work with him, but she'll never fall for him...no matter how fast he makes her heart beat or how thoughtful he is beneath his party persona. He's her client, and that's all he'll ever be. Right?
