What is the author's style in Children of the Flames: Dr. Josef Mengele and the Untold Story of the Twins of Auschwitz by Lucette Matalon Lagnado?

The novel is written subjectively, although it tries to remain objective. The authors of this book have become very close to the victims of Josef Mengele through research and, on the part of Sheila Cohn Dekel, marriage. The book gives a well researched biography of Josef Mengele, beginning with his childhood and continuing through most of his adult life. The book also offers many stories of the surviving children who were tortured and experimented on by Mengele. These stories, while told as honestly as possible, color the story and change it, reminding the reader constantly of the terrible things Mengele did and how it affected the survivors of his actions.
