¿Tis the season in bucolic Emerald Springs, Ohio. As a gift to her daughters, Aggie¿s mom has invited their former foster sister, Ginger, to join their Christmas reunion. A potential candidate for Sociopaths Anonymous, Ginger could make Aggie nostalgic for the chalk line. But when Ginger turns up deader than a drumstick, Aggie¿s sister is the logical suspect because she always resented her mother¿s attachment to Ginger. Aggie knows her sister is incapable of murder. But that won¿t convince the police. Now Aggie has to find the murderer. Someone who's decided there's a loophole in thou shalt not kill.
