New York Times bestselling author Robin Cook takes on the ripped-from-the-headlines topic of using DNA tracking to catch a killer in Genesis, an unforgettable medical thriller. When the body of social worker Kera Jacobsen shows up on Chief Medical Examiner Laurie Montgomerys autopsy table, it appears at first that she was the victim of a tragic drug overdose. But for Laurie and her new pathology resident, the brilliant but outspoken Dr. Aria Nichols, further investigation reveals an alarming discovery.
The young woman was ten weeks pregnant when she died, but nobody seems to know who the father was or whether he holds the key to Keras final moments alive. 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 dont want to be found.

Working with experts at a genealogy website based in New York, she plans to trace the foetuss DNA in the hopes of identifying the mystery father. After Keras closest friend is found murdered days later, the need for answers becomes critical. Because someone out there clearly doesnt want Keras secrets to come to light and if Aria gets any closer to the truth, she and Laurie face becoming targets for a ruthless killer.
