Sisters of the Raven

From the beloved author of the Benjamin January series comes "a provocative feminist fantasy" inspired by Native American lore (Publishers Weekly).
The Yellow City is in crisis. The wells are running dry, and the Sun Mages have been unable to call the rains. Frustrated Mages across the land can no longer work the magic that once ran their empire. Now the magic lies solely in the hands of a few women -- the first ever to have developed magical powers.
