Redemption in Indigo, by Karen Lord.
This was in the Hugo packet, as Lord is up for a Campbell Award for best new writer. (The Campbell is not a Hugo, it's just on the same ballot.)
A young woman is married to a foolish glutton, and she returns home to escape him. He finds her and follows her, and she attracts the attention of the djombi, a sort of spirit. A trickster djombi decides she's the best person to give the Chaos Stick to, and the djombi he stole it from finds out and takes Paama on an interesting trip.
It's told in the manner of a folk tale, with the narrator occasionally poking through the fourth wall. Since the novel was inspired by a Senegalese folk tale, that's appropriate.
It's an interesting read. Lord has a wry sense of humor, and she makes even the djombi with indigo skin who thinks humanity is a plague sympathetic. If you like folk tales, you should pick this up.
