A dark force is rising in London…

Sebastian Montcalm knows freedom for the first time in his life, but it has come at the cost of his father's soul. If he can learn to harness his uncontrollable sorcery then he might be able to save his father from a demon's grip, but every move he makes leads to failure. The only thing that gives him hope is the innocent touch of Cleo Sinclair, the woman he was forced to marry. But will his darkness drown out her light?

He could be her destruction…

Cleo knew her father only ever loved her for the power of her visions, but when he bartered her away in marriage to a man she'd never met, she realized how little value she truly had. Her husband, Sebastian, was nothing more than a dark warmth in her bed, a stranger who refused to touch her. But together, the two tortured souls found friendship. And now, when he needs her the most, he won't even look at her.

…Or she could be his salvation…

When Cleo receives a powerful vision of a darkness that threatens London, she knows she is the key to defeating it. Only by working together can she and Sebastian prevail. But is Sebastian the one who can end this prophetic doom, or the one bound to begin it?
