To Kill a Kettle Witch (Novel of the Mist-Torn Witches Book 4)

National bestselling author Barb Hendee returns to the world of  the Mist-Torn witches, as two sisters who can see the secrets of the past and the mysteries of the future begin a quest to save the family they never knew existed.…
 
Powerful prince Malcolm is facing ruin in the wake of a curse that has destroyed his harvest. He blames the band nomadic Móndyalítko who summer in the meadow below his castle—and he is determined to root out the people who caused the blight by any means necessary.
 
When Céline and Amelie Fawe, descended from the Móndyalítko, learn that their mother’s people are under suspicion of sabotage and treason, they set out to use their magical gifts to save their estranged relatives and learn about their own origins.
 
Now it’s up to the sisters—along with their motley escort, including a prince’s lieutenant, a shape-shifter, and an old woman with a murky past—to discover the  source of the curse to restore life to the ravaged land and protect the innocent from unfair vengeance.
