About This Book

For a man who has everything—money, charm, and a studiously uncomplicated life—Xavier Castillo is startlingly easy to underestimate. That's exactly how Sloane Kensington prefers it. As his publicist, she needs him manageable, not magnetic. But when circumstances force them past the comfortable distance of professional irritation, both of them have to reckon with something far more inconvenient than mutual antagonism. King of Sloth is the rare romance where the emotional stakes sneak up on you: what begins as sharp banter and strategic avoidance quietly becomes a story about ambition, grief, and two people who have built their entire identities around never needing anyone.

Ana Huang writes with a particular gift for pacing — she knows exactly when to let a scene breathe and when to pull the tension tight. The push-pull between Xavier and Sloane crackles with genuine wit rather than manufactured conflict, and the chemistry earns its slow burn. As the fourth installment in the Kings of Sin series, it works beautifully as a standalone while rewarding readers already invested in this world. The prose is smooth and propulsive, the kind that makes three hundred pages disappear before you've thought to check the time.
