The Devil's Shadow. Sister Witches, #2

Something has awakened that even the devil can't vanquish. Kicked out of her coven and at the devil's mercy, Hennie has been playing judge, jury, and executioner to the worst of the worst. When her flair for justice turns into an all-out bloodlust, it's time to call it quits, but giving up power is difficult. While Hennie struggles to retain the last vestiges of her morality, an ancient anger awakens inside the body of an innocent girl.
Since her power is useless, she must recruit her former friend to help fight this evil. Fueled by a new power source, Rachel and the coven are stronger than ever. In a rare moment of truce, Paula, Rachel, and Hennie reunite for one common goal. They must exorcise the trespasser before its evil spreads like a plague over humanity. Sister WitchesThe Devil's ShadowThe Devil's Soul
