Yrth… a place of ordered beauty -- and undreamed of terror. A magical realm where winged Amaranthine hide in the shadow of humankind, while selfishly exploiting them. A universe of countless dimensions; where an unwary sideways step might carry you to Death's silent Kingdom -- or beyond, to the very heart of the rising Gyre.
Now into this world comes Katrione Estelle du Chesne, a born healer. The Amaranthine need her, for she is destined to become the Vessel of the Goddess Lalluna and a pawn in the battle against their enemy, the dark Angellus. And Katrione's fellow citizens, in the nation of Beaumarais, are also desperately in need of a healing touch, as they suffer through an endlessly bloody civil war.
The difficult choices that Katrione must make -- between humankind and Amaranthine -- true love and responsibility -- sworn oath and unhappy truth, make for compulsive reading.
