Matrony. Protectors of the Elemental Magic, #5

Before the Protectors, there was a last attempt. It all began with the birth of three goddesses: radiant Danu of Light, steadfast Brighid of Balance, and Snowystra of Winter. After Snowystra turned on Danu, the four elemental beings of Air, Fire, Water, and Earth sought help where no god would think to look: among mortals. In the quiet town of Starten, four ordinary girls are gifted a spellbound book, its pages crafted to conceal a greater truth.
But after the deception is uncovered, the girls' salvation will demand courage not only from goddesses, but from those brave enough to claim the power placed in their hands. A mythical tale of magic and destiny, MATRONY is the fifth book in the Protectors of the Elemental Magic series by Marnie Cate.
