Foreboding A Black Eyed Witch Novel

The second book of The Black Eyed Witch series.
Lithia is a witch and possesses the natural inhuman strength, healing ability, and long lifespan that all witches have. Ronan, her lover, is a human royal guard and a former witch hunter. Together they travel the kingdom, hired by cities and villages to eliminate the creatures that prey on their citizens.
While defending a town against an attack, the humans inexplicably turn on them. When the battle is over, no human is left alive. Word of the bloodbath spreads, and enraged humans blame the witches for the deaths.
On the run and desperate for answers, every place they stop has new tales of similar massacres across the land. They discover a group of Naguals, hideous shape-shifting brutes, are behind the humans' attacks on witches. A race against time begins as Lithia and Ronan hunt the Naguals while being chased by the very humans they are trying to save. If they don't stop the Naguals, both humans and witches will be at their mercy and the world as they know it will be over.
