In the underground Fae realm, only the strongest and most ruthless have power, but a young human woman forced into a life of servitude is about to change everything. Kenna Heron is best known in her village for being a little wild—some say half feral—but she’ll need every ounce of that ferocity to survive captivity in the cruel Fae court. Trapped as a servant in the faeries’ underground kingdom of Mistei, Kenna must help her new mistress undertake six deadly trials, one for each branch of magic: Fire, Earth, Light, Void, Illusion, and Blood. If she succeeds, her mistress will gain immortality and become the heir to Earth House. If she doesn’t, the punishment is death—for both mistress and servant.

Kenna Heron is still reeling from her lover’s betrayal and the threat of an impending war. With only her two closest, and most powerless, friends by her side, she must navigate the treacherous politics of Mistei while coming to terms with her new identity as not just Fae, but princess of her own house. Old loyalties fray as new, dangerous alliances form, and Kenna finds herself caught in a web of violence, deceit, and unexpected passion. Kenna has the power to shape Mistei’s future, but someone is willing to kill to make sure she never gets the chance.
