"Seattle gallery owner Virginia Troy has spent years battling the demons that stem from her childhood time in a cult and the night a fire burned through the compound, killing her mother. And now one of her artists has taken her own life, but not before sending Virginia a last picture: a painting that makes Virginia doubt everything about the so-called suicide--and her own past. Like Virginia, private investigator Cabot Sutter was one of the children in the cult who survived that fire...and only he can help her now. As they struggle to unravel the clues in the painting, it becomes clear that someone thinks Virginia knows more than she does and that she must be stopped."--
