Saffyre is a girl that had a terrible thing happen at the age of 10. She goes to a child psychologist (Roan) for years and when he thinks she doesn't need him anymore, he stops their sessions. She feels invisible and feels she needs him more, so she starts stalking him and his family.
She learns some secrets and then disappears. No one know what happened and Owen, a professor that has been fired for sexual misconduct, comes in the crosshairs of the police. He swears he didn't do anything to her, but can't exactly remember. But can an invisible girl bring out the truth?

This book was kind of a slow burn and really dug into the "you don't really know a person" and those that seem good aren't always.
