Mist

Handmaiden Rya puts her life on the line to protect the royal family from an assassin. Lumini and all within the Shadow kingdoms are threatened by darkness far more sinister than any they have ever faced before. Battling the deadly mist, Sathen, and revelations about her past, Rya finds strength and love where she least expects it. But if the source of the Sathen can't be stopped, all of the races risk succumbing to the mist.
