The enemy has her. And the man she loves seems intent on using her dark magic to destroy her kingdom…

In the chaos of the magical assault on Pelias, Wren has been swept far from home. She is now a prisoner, in the heart of enemy territory. At least she has the man she loves beside her, keeping their passion alive during the cold nights in this unfamiliar place.

Or so she thought…

Finn has changed since returning to his father's kingdom. Instead of serving the princess he's proven his loyalty to time and again, he is keeping her under guard in a tower. Desire still lights up his eyes when he looks at her. But is he enamoured by Wren, or her power?

With the unfamiliar castle calling to her dark magic, Wren is fighting every minute to keep her growing power in check. And she struggles to ignore the still-smouldering heat between her and Finn every time their fingers touch – even as he keeps her under lock and key…

Is everything she believed about Finn a lie? Or is he under the influence of the dark power here too? And will she have time to figure it out before she's forced to turn her magic on her own kingdom?
