In the underground fae realm, only the strongest and most ruthless have power - but a young human forced into a life of servitude is about to change everything.
Kenna Heron is a servant in the faeries' underground kingdom of Mistei. Known in her village for being a little wild, Kenna must help her 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 them both. 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 secrets and passion. With time against her, 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.
