Kings of Sin in Order

The conceit is neat enough to carry the whole series: each hero embodies one sin, each book is named for it, and the sins double as a character brief. Wrath is the cold one, Pride the controlled one, Greed the one who wants everything, and so on.

The Kings of Sin books in order

1. King of Wrath (2022) — Dante Russo and Vivian Lau, bound by a blackmail-flavoured arranged engagement neither of them wanted. Sets the template: contract first, feelings later, everything expensive.
2. King of Pride (2023) — Kai Young, the impeccably controlled heir, and Isabella Valencia, who is not controlled at all. The lightest and funniest of the six.
3. King of Greed (2023) — Dominic Davenport and Alessandra — a marriage-in-crisis story rather than a courtship, and the most emotionally serious book in the series.
4. King of Sloth (2024) — Xavier Castillo, who has made indolence into a personality, and Sloane Kensington, who has made competence into one. Opposites, and a slower reveal than the title implies.
5. King of Envy (2025) — Dante's circle widens; the sin here is the quiet, corrosive kind rather than the dramatic kind.
6. King of Gluttony (2026) — The most recent instalment, published in April 2026.

A seventh, King of Lust, has been announced but is not yet published. Anyone listing it as available is ahead of the publisher.

Can you read them out of order?

More easily than Huang's Twisted series. Each Kings of Sin novel follows a different couple, and the connections are friendships and business relationships rather than a shared plot. Huang's own reading-order guidance treats them as standalones.

The reason to read in order anyway is the same as always: characters get engaged, married and into trouble in the background of each other's books, and reading forward means those developments arrive as news rather than as facts already settled. King of Greed in particular is much stronger if you have watched that marriage from the outside in book one.

Kings of Sin or Twisted first?

Twisted is the shorter, older and tighter series — four books, one friend group, complete. Kings of Sin is longer, glossier and still running, with a different couple each time and a wider cast.

If you want a finished story, start with Twisted. If you want the series that will keep producing books, start here. Both sit in the same universe and both contain nods to the other, but neither requires the other.

One practical difference: Kings of Sin heroes are older and further into their careers than the Twisted cast, and the books lean harder on business and family-obligation plots than on friendship-group dynamics. That makes each instalment more self-contained — and it is why the standalone framing genuinely holds here in a way it does not for the earlier series.

What to read alongside

The arranged-engagement and marriage-in-trouble plots that power this series are historical romance's oldest stock in trade. If the contract-marriage structure is what you are here for, the marriage of convenience shelf runs several centuries deep, and blackmail romance covers the sharper end of it.
