Graevale (Medoran Chronicles Book 4) by Lynette Noni
"Light or dark, only one can win. This world cannot survive in shades of grey." Now that Aven Dalmarta sits upon the throne of Meya, Alex is in a race against the clock to save the mortals of Medora from the Rebel Prince's wrath.
Guided by a haunting and unspeakable vision of the future, Alex and her friends must warn the mortal races. But making new allies out of old enemies proves difficult. Under the guidance of a mysterious mentor, Alex learns to strengthen her gift to fight the challenges she now faces.
But in a world where nothing is certain, Alex is sure of only one thing: Aven is coming.
I can say that Graevale deserves a full five stars and will forever be my favourite book in the series.
