Below Forsaken Mountain, a revolution stirs with the aim to overthrow the tyrant king of Trollus, and Marc is the right hand of its leader. It's a secret more than one troll would kill to possess, which is why he must keep it from everyone, even the girl he loves.

Since a tragic accident revealed her affliction and ruined her sister's chance at the throne, Penelope is an anathema to her father, the Duke d'Angouleme. Deeming her life worthless, he gives her one chance to survive: find proof that the boy she loves is a leader in the sympathizer revolution.

Marc and Penelope must navigate the complex politics of Trollus, where powers on all sides are intent on using them as pawns, forcing them to risk everything for a chance at a life together.
