The girl with the touch of ice and heart of steel. Ever since Wynter woke in the river that has stolen more lives than the harsh mountains of the North, she has been cast from town after town for her deadly touch. An exiled assassin. Niav used to be the most notorious assassin in the Mortal Lands-until the king she served killed the only leverage he had over her and she fled to the North, determined to never be someone else's tool again. When a fellow immortal by the name Evander offers them a chance at retribution, they are more than happy to accept. A rebel set on overthrowing them all. After the brutal death of his parents, Kieran is hellbent on finishing what they started: ridding the North of the immortals once and for all-including the infamous Ice Queen. All three of their fates are entwined when Evander takes his tyranny too far, spurring Kieran and the rebels into action. But after a fateful encounter with the Ice Queen, Kieran's perception of what is good and evil is flipped on its head, and he starts to wonder whether she could be the key to their salvation. Little do they know, Evander has plans far beyond what any of them imagined. Plans that could unleash evils that have been slumbering for centuries-evils that were locked away for a reason.
