What this book is about

Jeannie Ferrami is a criminologist studying criminal behavior in twins when she discovers something impossible: two men with the same DNA who have never met. Her investigation into how this happened — and what she herself might be — leads her into corporate conspiracy and personal danger. Follett's thriller is taut and scientifically grounded.
