Jones uses an interesting writing style to portray the not widely known circumstances of slaveowning free blacks. His characterizations are strong and the reader is compelled to consider what thought process (and abandonment of ethics) a human being might undergo in order to enslave his or her own kind. The questions raised by Mr. Jones' story, which is apparently well researched, are fundamental to those who question how (or whether) the human race is evolving ethically. Some may find the persistent flashbacks and flash forwards disconcerting but Mr. Jones' book is so interesting and thought provoking that one realizes that the writing style is integral to this reading experience.
