Nothing in Cree's training as a Harvard-trained clinical psychologist or her experience as a paranormal investigator has prepared her for Tommy Keeday’s case. A talented young Navajo, Tommy has recently been exhibiting bizarre symptoms that his family believes are signs of possession by a chindi, a hostile spirit. As Cree struggles to find answers, she becomes increasingly aware that Tommy and the people who surround him have some deep and disturbing secrets.
