The Griffin Mage Trilogy, omnibusRachel Neumeier2011

Little ever happens in the quiet villages of peaceful Feierabiand. The course of Kes' life seems set: she'll grow up to be an herb-woman and healer for the village of Minas Ford, never quite fitting in but always more or less accepted. And she's content with that path -- or she thinks she is. Until the day the griffins come down from the mountains, bringing with them the fiery wind of their desert and a desperate need for a healer. But what the griffins need is a healer who is not quite human . . . or a healer who can be made into something not quite human.
