Hawthorn — Carol Goodman

A world on the brink of war.
 
All Avaline Hall wants is to enjoy her senior year at Blythewood Academy, the boarding school where she's been trained to defend humankind from forces of dark magic. But when Ava is shown a glimpse into the future in the enchanted Blythe Wood, she discovers that the evil Judicus van Drood is rallying nations into a war that seems destined to destroy both the human and faerie worlds. Only Ava and her allies have a chance at stopping van Drood, but how many must die in the process? And how can Ava and the boy she loves be together when everything around them is falling apart?
