King of Envy is for billionaire-romance readers who want the forbidden part to be the real center: a scarred, solitary man falls for the fiancée of his oldest friend, and the engagement is not what it looks like. This is Ana Huang’s Kings of Sin novel, separate from Sandra Brown’s Envy and its publishing-world mystery.
Two people and a best man
Huang’s page for the book introduces Vuk Markovic as a scarred, reclusive billionaire notorious for shunning human interaction. The page says he saw her first and wanted her first, calls her the object of his obsession, and notes that she is now engaged to his oldest friend. As the wedding approaches, he struggles between loyalty and desire.
She is Ayana Kidane, a supermodel whose life looks perfect from the outside. The engagement, though, is a business arrangement with one of New York’s most eligible bachelors. He receives an inheritance when they marry, and she receives the money she needs to leave an abusive agency. Ayana finds herself drawn to her fiancé’s best man. When her wedding falls into chaos, she turns to Vuk for comfort, and his past threatens them both.

Who benefits from the arrangement?
The book’s obsession, wealth and loyalty conflicts are worth separating. The obsession belongs to Vuk, who the page says wanted her first, and who is now the best man at his friend’s wedding. The wealth shapes Ayana’s options: a marriage that pays is the way out of a situation she cannot leave otherwise. The loyalty is Vuk’s toward a friend, and the page frames it as a real counterweight to his desire.
What the page does well is give each lead a different reason to hesitate. Vuk’s barrier is a friendship. Ayana’s is a business arrangement that carries her way out of the agency. Neither can act on attraction without consequences for someone else, which is the engine of most forbidden-romance plots.
The fiancé is the one major figure the page leaves unnamed, describing him only as Vuk’s oldest friend and one of the city’s most eligible bachelors. How sympathetic or villainous the book makes him is not stated, so any reading about his role belongs to the book.
Series, tropes and reading order
Huang places King of Envy as the fifth book in the Kings of Sin series, with an April 2025 release. Her reading-order page lists the seven books in publication order and says her series can be read apart from each other, with the occasional cameo. It does not say whether the Kings of Sin books should be read in sequence. The book page lists the billionaire trope. There is no listed point of view or structure on the page, so the opening chapters will show it.
Scar, solitude and a wedding
Vuk’s description is the most atmospheric part of the page: scarred, reclusive, notorious for shunning human interaction. Those details set up a hero who watches from the edge of his own life, and they make his role as best man pointed. A best man stands up for a friend in public while, here, wanting the bride. The page frames his struggle as loyalty against desire, a clean statement of the conflict that a book can pursue in many tones, from tender to tortured.
Ayana’s description pulls the other way. She is a supermodel whose life looks perfect, in an arrangement the page says is about money and an inheritance. The contrast between a polished public image and a private need is the part of the premise that may give her more depth than the glamour suggests. When her wedding falls into chaos, the page says she turns to Vuk for comfort, so the book is about who she can rely on when the arrangement fails as well as about desire.
The last line of the description, that his past threatens them both, signals that the conflict is not only about the wedding. It promises a second source of danger arriving through him. The content notes for death, murder, torture and arson suggest the threat may be serious, though the page does not map the notes onto the plot.
What readers praise
Readers on a major book-review site rate King of Envy at about 4 stars from more than 175,000 ratings, with roughly three in four giving four or five. Most of the praise goes to Vuk. Fans call him brooding, scarred and intensely possessive, point to his protectiveness and quiet devotion, and many name him their favorite of Huang’s heroes. Ayana is described as smart, confident and no doormat, and readers also like her warm family scenes.
The slow burn and yearning between them are the most-praised elements, with several readers calling the push and pull addictive. Enthusiasm also runs to the best-friend’s-fiancée setup, the forced-proximity and one-bed moments and the morally gray hero. Several reviewers find the intimate scenes hot and well balanced with the romance, though not everyone agrees on heat, and a few say the plot’s suspense and action kept them invested alongside it.

Content notes
Huang publishes content notes for each book. For King of Envy they list sexual harassment and assault, death and murder, torture, arson and financial abuse. Those are significant, and they sit alongside a premise that already involves an abusive agency and an engagement that serves as the heroine’s route out of it. The page does not describe where in the book they occur, how they are treated, or how explicit the intimate scenes are. Check the current edition’s content notes before deciding.
Who this is for
Readers who like a hero who watches from the edge, a heroine with a practical reason for a public engagement, and a wedding that slowly unravels will find a clear promise. Readers who dislike betrayal triangles, who want an unattached heroine, or who find torture, harassment and financial abuse hard to read about, may be better served by the notes first and perhaps a different book.
The opening chapters can answer a few specific questions:
- Ayana’s agency: whether she makes and owns her choices about the arrangement, not only reacts to them.
- Vuk’s reclusion: whether his solitude and scars feel like character rather than a costume for the broody-hero role.
- The friendship: whether the loyalty he feels is built with enough warmth that its breach matters.
- The money: whether the financial terms are specific enough that you understand why Ayana accepts them.
Reading alongside Terms and Conditions
Lauren Asher’s Terms and Conditions also builds a romance around an inheritance clause. Its publisher description follows Declan, who must marry and have an heir to meet his grandfather’s inheritance clause and become CEO of his family’s media company, and whose assistant, Iris, offers to become his fake wife. As they perform a public romance under a contract with rules, the arrangement starts to blur into real feelings. The difference is who is at the center. In Asher’s book the people who sign the contract are the couple. In Huang’s, the bargain belongs to Ayana and her fiancé, and the romance runs to a third person.
From the shelf: a marriage proposal, and a free workshop story
Bought by the CEO by Alisson Bento introduces librarian Jessica, who faces an archive’s debt deadline when Erasmus proposes a marriage that serves his public image. It connects through money shaping the terms of a public relationship, but it differs through a darker, direct financial bargain with the proposed husband, rather than attraction to an intended groom’s friend. Browse the billionaire romance shelf to compare.
The Terms of Staying is a free original adult M/F story pairing restorer Mara Vale and Adrian Voss around workshop debt and one public evening. It is a thematic companion before Bought by the CEO, not a story about Jessica and Erasmus, and its intimacy is closed-door. Its leads are original and have no connection to the cast of King of Envy. Read online; email access unlocks later chapters.
