"Hello, Katriona."

Those two words spark fear in Katriona Wilde and give way to an unlikely partnership with Perth, the man she's been traded to marry for a favor. Saving her true love and protector Arland, her family, and their soldiers keeps her motivated, but the at-odds duo soon realizes trust is something that comes and goes with each breath of Encardia's rotting, stagnant air.

The moment when concern for her missing sister spirals out of control, all thoughts of trust are pushed aside and she finds herself trapped by the daemon tricks Perth warned her of.

When so many she's grown fond of die along the journey, will she still be Katriona Wilde, the girl with fire?
