Stella O'Neill is just your average millennial, working at a public library and worrying about making rent. No one would suspect she's been living under an assumed name or that she was raised in a Vermont commune of "diviners" where, and as a ten-year-old, she witnessed her mother's brutal murder--a crime that has gone unsolved for years. But her quiet, anonymous existence is upended when a true-crime obsessive posts her current name and location on the internet. Now, Stella has to get out of Boston before her mother's killer can find her and finish the job he started all those years ago. Fed up with living in fear, she heads to the off-the-grid retreat of her childhood to confront her mother's unhinged guru who controlled their lives for so long--the infamous Radcliffe MacBeath. Stella has two powerful assets: determination and a supernatural gift. Relying on her mother's beloved rose quartz pendulum, Stella will have to outwit the charismatic leader who's ruined so many lives and discover once and for all the true identity of her mother's killer--before becoming his next victim.
