The elven Court of Stone has many spies, and Kenna is one of its most prized ones. Being a half-elf, she is skilled, dangerous, and beautiful. She's also a traitor. Desperately yearning for freedom, she blackmails people for ransom behind the back of the elven prince who holds her leash. But one day, she takes it too far. When she accidentally goes after someone from a neighboring court, she is cornered by its prince. The feared Prince of Shadows gives her an ultimatum: spy for him on her own court or her master will learn of her illegal activities.

At the same time, a legendary weapon resurfaces that Kenna has to find for the Prince of Stone. But when things don't go according to plan, he discovers that there is a traitor in their midst and calls in his most trusted spy to root out the hidden enemy. Kenna now has to maneuver between two lethal elven princes, a ruthless spy turned traitor hunter, and a mission to seduce an unwitting member of a third court before a magical dagger is used to kill the King of Elves. All while still trying to blackmail her way to freedom.

Death awaits her on all sides should she fail. Will she survive this dangerous game? Or will her head–and her heart–lead her straight to ruination?
