Bright and engaging fantasy, Nightspell is moving, thoughtful, and a little strange. A princess is to be married to a prince of a nearby kingdom, nothing new there, but besides the standard courtly murder and intrigue, there are ghosts who are indistinguishable from the living. Our heroine, a warrior from sun filled plains, goes to this dark forbidding place to save her sister who was sent here as a child. Who is dead? Who is alive? Does it even matter? Beautiful book, sad and lovely and complicated and inventive.
