When Mathieu followed his king to war, he knew the
Crusades were holy, that God went with him, and that
he would return to the arms of his truest love. 800 years
later, enslaved by the demon Gadreel, all Mathieu knows
is pain.

After winning his freedom, Mathieu emerges from the
dark void of captivity, only to find himself facing the soul
of the love he left behind, in the eyes of Jenn Bartlett. Can
he do the terrifying thing she asks of him, and still save
her from the monster he has become? Or will the darkness
overcome them both?
