Never trust a witch.
For four hundred years, generations of the Family Del Toro and their battle-savvy warhorses have secretly guarded their corner of Colorado from savage packs of hairless wolf-like creatures known as skinners. Now that those meat mutts are locked away, twelve-year-old Matt Del Toro and his father and brother are hoping to live a more normal life.
Normal isn’t going to happen. Not when a mysterious woman with some wicked witch powers shows up at the Del Toro ranch and demands the return of the Red Casket—a medieval iron chest that contains something best kept under lock and key.
With his family in danger, Matt must team up with his best friend Perry, and the warhorses Rigo and Isabel, to out-wit, out-ride, and out-fight one Viking-size sorceress.
