How many letters does it take to spell out the truth?

Evie has a gift - a gift she's not always comfortable with. But when Alex suggests they conduct a séance, Evie reluctantly agrees. The letters on the board start spelling out one name - C-A-Z - over and over, and Evie knows she's been contacted again. A cryptic message with nine letters leads Evie to a family where two sisters, one living, one dead, share a dark secret that must be revealed.

But is Evie strong enough to solve the mystery and reveal the truth in time to release both girls?
