Princes of Sin Books in Order

The Princes of Sin series takes the demon princes introduced in Kingdom of the Wicked and gives them center stage in a run of adult romantic fantasies. Each book focuses on a different prince, pairing his particular sin with a heroine who refuses to be overwhelmed by it.

Throne of the Fallen follows Envy, whose court is slowly collapsing under a mysterious curse that steals memories. When the Unseelie king forces him into a deadly game built around riddles and hexed artifacts, Envy is drawn to Camilla Antonius, a mortal painter and gallery owner in the human town of Waverly Green. She is already drowning in blackmail and forgery, and agreeing to help him with the Hexed Throne drags her into demon courts, vampire politics, and the truth about her own magic.

In Throne of Secrets the spotlight shifts north to Prince Gluttony, notorious for reckless pleasures, dragon hunts, and scandalous parties. After an ice dragon attack hints at something deeply wrong in his territory, he stages a competition to find a bride as a distraction. Adriana Saint Lucent, the sharp journalist who has made a career out of mocking him in print, moves into House Gluttony to support her sister and dig up the real story, only to find that her history with the prince is more tangled than she imagined.

Throne of Nightmares turns to Prince Sloth, a book obsessed ruler who would rather hide in his enchanted library than deal with politics. A forgotten deity and a cursed volume called the Book of Nightmares threaten the very structure of the Underworld, forcing Sloth into a quest with Lore Brimstone, a human librarian who is suddenly dropped into his world. As they step through twisted versions of her favorite stories, they have to keep the borders between gods and mortals from collapsing.

Across the series the tone is indulgent and dangerous, full of enchanted objects, elaborate courts, and romantic tension that simmers for chapters before finally breaking. The books are written to function as standalones, but reading them in publication order, starting with Envy then Gluttony and Sloth, lets you watch ongoing threads about the gods, the fae, and the princes' complicated family dynamics unfold in the background.

If you have already finished the Kingdom of the Wicked trilogy, these novels offer a richer, darker tour of the same world, with higher stakes, older characters, and a stronger focus on the love stories.
