Killer Twin
Twin 3-year-old sisters Kendra and Amber were separated when Kendra was adopted out of Bridges Orphanage and into the loving Collins family.
Kendra has led a good life; 30 years later she is a respected teacher married to handsome, devoted architect Dane Walker; they live in a nice home in a nice Seattle neighborhood, and they're expecting their first child.
The orphanage's abusive matron Eunice deemed Amber the problem sister; she was never adopted and she turned to a life of crime.
While Kendra has no remembrance of any biological sister, let alone a twin, Amber remembers Kendra well.
When Amber discovers Kendra's whereabouts and the fantasy life she has, Amber is determined to have what she feels she was deprived of by assuming Kendra's life, thus putting Kendra's identity--and whole life--at risk.
