Book One of a planned fantasy trilogy
Reva has spent her life holding together a house that is slowly coming apart. With her father fading under the weight of the Marred and her mother working herself to exhaustion, Reva answers the Iron Call and leaves home before dawn, hoping the Oath can make her into something strong enough to save them.
But the Iron Oath is harsher than rumor, and the Threshold is only the beginning. As Reva is sorted into Thorn Company, old feelings resurface with Hadden, a boy from her past who sees too much and says too little. And when one of the Oath’s iron-bound hounds marks her in front of the recruits, Reva realizes the world she has entered may already know something about her that she does not.
