Princess Katya Nar Umbriel's uncle Roland rose from the grave, kidnapped her cousin, and stripped her of her greatest weaponher Fiendish power. Without her Fiend, Katya doubts her ability to weather the storm her uncle is brewing. When she lacks what even the children in her family possess, can she even call herself an Umbriel?

In only a short time, Starbride has become the princess consort, a pyradisté, and a member of a secret order in charge of protecting the crown. Even steeped in responsibility, she's still an outsider. While wading through court intrigue and resisting schemes to break her bond with Katya, Starbride must prepare for a covert war. Roland is waiting, watching, ready for any chink in their armor, and he doesn't care who knows their secrets.

To most, Princess Katya Nar Umbriel is a rogue and a layabout; she parties, she hunts and she breaks women's hearts. But when the festival lights go down and the palace slumbers, Katya chases traitors to the crown and protects the kingdom's greatest secret: the royal Umbriels are part Fiend. When Katya thwarts an attempt to expose the king's monstrous side, she uncovers a plot to let the Fiends out to play.

Starbride has no interest in being a courtier. Ignoring her mother's order to snare an influential spouse, she comes to court only to study law. But a flirtatious rake of a princess proves hard to resist, and Starbride is pulled into a world of secrets that leaves little room for honesty or love, a world neither woman may survive.

No pirate on the high seas is more bloodthirsty than the notorious Branded Ann, a woman with eyes like ice and a face marred by a mysterious cross-shaped scar. When she raids a merchant vessel bound for Jamaica, her only objective is to obtain the map that will lead her to a legendary treasure. But she hadn't bargained on taking Violet, the merchant's young widow, on board her ship as a prisoner. In spite of her childlike appearance, Violet has a dark side of her own that Ann finds both infuriating and endearing.

As Branded Ann sails in search of treasure, her task is made more difficult by a stowaway child, an increasingly rebellious crew, and the treacherous seas of the Devil's Triangle; to make matters worse, she finds herself falling for her not-so-innocent but altogether charming captive. But will Violet be able to overcome the demons of her past and accept Ann's love? And will they survive the treasure hunt that has already claimed the lives of so many before them?
