Summary: Kat Connors is 17 years old when her perfect homemaker mother, Eve, a beautiful, enigmatic, and haunted woman, disappears - just as Kat is discovering and relishing her newfound sexuality.

In fact, it's almost a relief. But as time passes, Kat begins to come to grips with how deeply Eve's disappearance has affected her. Returning home on a break from college, she finds herself confronted with the truth about her mother's departure, and her own denial about the events surrounding it...
