The Dividing: A Dystopian Fantasy Series (The Adamic Trilogy Book 1) by Devin Downing
Hunger Games meets Throne of Glass.
In Cavernum, only the elite have access to magic, yet status must be earned. One's class is determined by a single competition: The Dividing.
Matt is a refugee; Rose is the future queen. Turning 18, each must compete for their spot in society, and each is desperate to succeed. For Rose, magic is the surest way to secure her crown. For Matt, it’s the only way to save his dying mother.
But danger lurks beyond the city walls, and Cavernum won’t be safe for long.
