While Laurie faces a personal crisis with the support of her husband, forensic pathologist Jack Stapleton, the impulsive Aria investigates a controversial new technique to progress the case: using DNA databases to track down those who don’t want to be found. Working with experts at a genealogy website based in New York, she plans to trace the foetus’s DNA in the hopes of identifying the mystery father.
After Kera’s closest friend is found murdered days later, the need for answers becomes critical. Because someone out
there clearly doesn’t want Kera’s secrets to come to light and if Aria gets any closer to the truth, she and Laurie face becoming targets for a ruthless killer.
