Season of the Witch is a mystery novel unlike any other. Gabriel Blackstone is a "remote viewer," a skill that allows him to tap into someone else's surrounding energy and "relive" their experiences. However, Gabriel had resigned from the craft after an unfortunate and horrifying experience. Or so he thought. Now a thief and hacker living it big in London, Gabriel receives an offer from a very wealthy man. He asks Gabriel to find out what happened to his son, who has been missing for a while. With much pushing and prodding from Gabriel's ex- girlfriend, Frankie (who is the old man's new wife), Gabriel is convinced to help the couple out. Gabriel's search leads him to the Monk sisters, Minnaloushe and Morrighan; unusual names for unusual women. Entranced by the sisters, Gabriel spends almost every waking moment with them. Then the tide turns. Gabriel learns that the Monk sisters have a very dark and mysterious past, one that Gabriel is now trapped in.
