The Origin of Storms by Elizabeth Bear
“The Origin of Storms is a rich and satisfying conclusion to the trilogy, which began with The Stone in the Skull and The Red-Stained Wings. This trilogy is linked to and set in the same universe as Bear’s earlier Eternal Sky books – but these three titles make for a satisfying arc all on their own. If you want more in this world, however, there are three more books worth of epic goodness to pick from.” — Locus
