Updraft by Fran Wilde

Kirit Densira lives in a remarkable world, high above the clouds, in towers made of living, growing bone. She is ready for her wing test, and hopes to be her mother’s apprentice. Ezarit is a trader who soars between towers. Kirit’s curiosity puts her in danger, and causes heavy penalties for her and her wing brother Nat. Kirit’s harsh singing voice may be surprisingly useful, and the Singers of the Spire want her to join them, but it’s hard to know who to trust. Full of adventure and intrigue, soaring heights and monsters in a suspenseful and compelling fantasy. I really enjoyed Kirit’s story, and look forward to reading about Nat in Cloudbound. I think fans of Anne McCaffrey’s Harper Hall trilogy, which begins with Dragonsong, would enjoy Updraft, which won the Andre Norton award.
