They know who you are. Let me help you. When Chicago advertising executive Michael Janaseck reads the unsettling email on his computer, and learns of the menacing visitor to his office, he is disturbed, mystified and angered by the assault on his privacy. Days later, a stranger is murdered before his eyes in his own back yard, and Michael's anger turns to panic as his safe and sane suburban life spirals out of control. Hunted because of "who he is' by relentless pursuers that kill everyone trying to protect him, searching for a mother he never knew existed, wanted by the police, Michael finds himself adapting to a world of violence and terror at a pace he never imagined possible. DNA is the story of an average man coping with unaccustomed violence and danger. It is also the tale of a search for hidden ancestry. In the end, genetic imprinting reveals how each of us may be nothing like who we think we are.
