Cure the plague. Save the kingdom. But first, survive each other. Mercy betrayed the Guild to save Prince Tamriel’s life, and now the Assassins will never stop hunting them both. She’s desperate to keep him alive, but how can she do that when he can’t even stand the sight of her? Calum ’s plans to avenge his father’s murder were thwarted when Mercy broke her sacred oath. He’s terrified she will tell Tamriel about his betrayal—and he’ll kill to keep his secret safe. Tamriel must accompany them to the wild and war-torn Cirisor Islands if he wants to cure the deadly plague sweeping his country. With Mercy and Calum constantly at each other’s throats, it doesn’t take long before their group begins to crumble. They’ll do anything to save Tamriel’s people and right the mad king’s wrongs, but first they have to survive the Islands—and each other.
