The “Kings of Sin” series by Ana Huang is a dark romance series that focuses on a group of powerful men, each with their own personal demons, secrets, and a deep connection to their past. The series is known for its intense chemistry, morally gray characters, and suspenseful plots. Here’s a summary of the books in the series:
1. King of Wrath (Book 1)
King of Wrath is the first book in the series and follows Valentina “Tina” Cabrera and Aurelia “Leo” De La Cruz. Leo is a ruthless, wealthy, and powerful businessman with ties to the criminal world. He is the embodiment of Wrath, one of the Seven Deadly Sins, and has built his empire through ruthless determination and control.
Tina, on the other hand, is a strong-willed, independent woman who has been forced into a marriage of convenience with Leo due to her family’s financial troubles. The marriage is purely transactional, and Tina initially resents the man she’s been married off to. However, as they spend more time together, Tina begins to see a different side of Leo — a man burdened by his past, who hides his vulnerabilities beneath his icy exterior.
The story revolves around their forced marriage, simmering tension, and the slow-burn romance between them. Despite their differences, they begin to develop mutual respect, passion, and a deeper connection. But their relationship is complicated by Leo’s dark secrets, including his criminal activities, and Tina must decide whether she can trust him or if she’s being manipulated. King of Wrath explores themes of power, control, betrayal, and trust.
2. King of Pride (Book 2)
In King of Pride, we meet Lorenzo “Loren” De La Cruz, Leo’s older brother, and Ava Delgado. Loren is a brooding, prideful, and fiercely protective man, who, like his brother, has a dark past. Loren is the personification of Pride, and he has always struggled with the expectations placed on him as the heir to the De La Cruz family empire.
Ava is a woman with a secret, trying to keep a low profile due to her own dangerous past. She’s forced to work for Loren after he discovers her secret, but what starts as a hostile working relationship soon develops into something much more complicated. Loren’s pride and arrogance often clash with Ava’s independent nature, but the sparks between them are undeniable.
As Ava and Loren get closer, they both uncover hidden truths about each other’s pasts, which threaten to tear them apart. Loren’s pride and unyielding need for control, combined with Ava’s vulnerability, create a compelling push-and-pull dynamic. King of Pride dives deep into themes of redemption, self-worth, and the complexities of family loyalty, all wrapped up in a high-stakes, passionate romance.
3. King of Greed (Book 3)
The third book in the series, King of Greed, introduces Rafael “Rafe” De La Cruz, Leo and Loren’s younger brother, and Elena Vargas. Rafe is the embodiment of Greed, and he is as ruthless and calculating as his older brothers. He is known for his business acumen, manipulating situations to his advantage, and using his wealth and power to get what he wants.
Elena, on the other hand, is a brilliant and ambitious woman, who has always struggled to balance her career and her personal life. She’s a woman who values independence and success, but when her path crosses with Rafe’s, her life takes an unexpected turn. Rafe sees Elena as a challenge — someone he can control, but also someone who intrigues him in ways no other woman has.
Their relationship begins with an undeniable attraction, but Rafe’s manipulative tendencies and Elena’s refusal to be controlled create friction. As their romance deepens, Elena realizes that Rafe’s greed and desire for power are part of the reason he keeps pushing her away. However, Elena’s own ambitions force her to confront her feelings for Rafe and the dark sides of his personality.
King of Greed explores themes of ambition, control, and vulnerability, with a fiery romance at its core. Both characters must navigate their desires for power and love while confronting their personal demons and deciding if they can trust each other.

4. King of Sloth (Book 4)
Theo De La Cruz is the embodiment of Sloth, and his personality perfectly reflects this deadly sin. He is the youngest of the De La Cruz brothers and is known for being laid-back, relaxed, and disinterested in the intense world of power and control that defines his brothers’ lives. While his siblings are heavily involved in the family’s business and criminal empire, Theo tends to keep to the sidelines, preferring to live a life of luxury without the burdens of leadership or responsibility.
Despite his easygoing persona, Theo has his own emotional baggage and struggles with finding meaning in his life. His apathy towards work and relationships masks deeper issues—particularly his sense of inadequacy and fear of being trapped by the weight of his family’s expectations.
The story picks up when Lena King enters Theo’s life. Lena is a determined, ambitious, and fiery woman who has her own past traumas and goals. She is determined to carve out a path for herself, separate from her family’s legacy, and is initially uninterested in Theo’s charm or wealth. But when circumstances force them into close proximity, their relationship begins to develop in ways neither expected.
At first, Lena sees Theo as lazy and unmotivated, someone who doesn’t take life seriously. However, as she gets to know him better, she begins to uncover the layers beneath his slothful exterior. Theo, despite his apparent lack of ambition, is hiding emotional scars and a deep-seated fear of failure. As their romance evolves, both Theo and Lena are forced to confront their pasts, their desires, and their feelings for one another.
Their relationship becomes a journey of self-discovery for both characters, as Theo learns to embrace responsibility and stop running from his emotions, and Lena begins to let go of her fears about trusting someone else with her heart.
