As their rivalry grows and he grapples with the responsibility of leading the Order of Daggers, he feels himself slipping further from who he wants to be. Is he doomed to a life in the shadows? Or can he forge another path? Meanwhile, rebellion is stirring in the kingdom and a dangerous prince grows in power.
