King of Sloth

Ana Huang's King of Sloth centers on Xavier Castillo, a charming billionaire heir who resists taking responsibility for his family's empire, and Sloane Kensington, the disciplined publicist employed to manage his image. Their professional relationship is built on friction: Xavier treats rules as optional, whereas Sloane has organized her career around control and competence. A family tragedy and a negotiated period of closer contact make it harder for either of them to keep attraction separate from work.

The novel develops its romance through the contrast between public persona and private need. Sloane sees the costs of Xavier's apparent aimlessness, including the expectations attached to wealth and inheritance; Xavier recognizes how ambition has protected Sloane while narrowing the space she allows for vulnerability. Their client-publicist arrangement also creates an ethical boundary that desire alone cannot erase, giving reputation and trust practical stakes.

As the fourth Kings of Sin novel, this volume tells a complete central relationship within the shared series world. Huang uses banter, forced proximity, travel, and high-society settings to test whether the leads can act beyond the roles that make them legible to others. Its emotional arc turns less on changing one person for another than on accepting responsibility without surrendering individuality.
