These chapters are the ones in which Tarisai finds out a ton of truths, large and small, about her mother. She finds out that she herself has the Ray, and that none of her friends are surprised. And she finds out that there's no way (none that the Lady knows of, anyway) to keep the Songland kids from being the ones sacrificed.
The song is Akadiole by Sekou Conde featuring Mamadama Conde. Sekou Conde is a teacher of West African traditional drumming, and you can find him on Facebook here, as well as virtually attend classes! https://www.facebook.com/faradalaconde/
Mamadama Conde is a member of Nimbaya!, an all-women Guinean drumming group practicing a drumming tradition that had previously only been permitted to be performed by men. You can find them on Facebook here! https://www.facebook.com/profile.php?id=100063538394338
