In a bleak borderland village where survival means fending off monstrous night raids, Catherine Mitchell is accustomed to picking up the pieces. With her hands stained from saving a loyal hound after a brutal creature attack, Catherine relies on her sharp instincts and healer's touch to endure a dangerous life on the edge of the human world. Her fiercely protective older brother, Raymond, leads the local patrol, but even his authority cannot hold back the tide of what lies beyond the boundary stones. When the morning mist parts to reveal a silent, silver procession of Fae riders crossing into the village, the ordinary threat of monsters pales in comparison. The villagers know better than to linger when the Fae arrive. But as terror grips the yard and Raymond orders her to flee inside, the stubborn healer stands her ground to observe the incoming threat.
