Kenna Heron is a servant in the cruel underground faerie kingdom of Mistei. There she must help her mistress undertake six deadly trials, one for each branch of magic: Fire, Earth, Light, Void, Illusion, and Blood. If Kenna succeeds, her mistress will gain immortality and become the heir to Earth House. Fail, and they both die. With only a sentient dagger of mysterious origins, Kenna must face monsters, magic, and harrowing tests . . . But worse dangers wait underground, and soon Kenna gets caught up in a rebellion against the sadistic faerie king. When her feelings for the rebellion's leader turn passionate, Kenna must decide if she's willing to risk her life for a better world and a chance at happiness. Surviving the trials will take cunning, courage, and an iron will . . . but even that may not be enough.
