About the title
Marcy decides to give an original Christmas gift — she buys DNA test kits for all her relatives. She's eager to learn more about her origins and family tree. But her loved ones' reaction turns out to be far from joyful. Soon Marcy understands why: one by one, her relatives begin dying under mysterious circumstances. The connection is obvious: all the victims took DNA tests. Someone is desperately trying to hide a dark secret — and is willing to kill to keep the truth from ever coming out.
