On the eve of her twenty-fifth birthday, Ava receives the strangest invitation of her life, promising an event she's never heard of: The Chosen Ball in a place called Ferri.
What begins as an odd curiosity turns into a leap through a magical portal... straight into the underworld. The ball turns out to be a front for the princes to find the one person who can resist them all-to break the curse and set them free.

And Ava didn't just resist all seven sins-she slapped one in the face. Now, she's caught the attention of all seven princes.
With clever banter, unexpected allies, and dangers that aren't always what they seem, Ava must navigate her way through staying with each prince, dodge the temptations of its charmingly infuriating princes, and uncover the truth behind the curse before the clock runs out.

But Ferri isn't all fire and brimstone-it's a place with thriving nature and quaint towns, and seven cursed princes, each tied to one of the deadly sins.
Seven sins. One sharp-tongued mortal. And a journey where the biggest risk is losing yourself-heart and soul.

Ferri is more than a prison. And its princes are more than monsters.
