This is a very difficult book to read. Not that it is poorly written; the writing is some of David Morrell's best. However, the story is very disturbing and, at times, gut wrenching.
Testament was Morrell's second published novel, following the success of First Blood, the book that introduced Rambo. It is the story of a man who has made mistakes in his life. His first was having an affair with another woman, an event that nearly destroyed his marriage. His second mistake was writing an unflattering magazine article about the leader of a right-wing extremist group. In retaliation, that group marked him and his family for death.
This book starts with a heart-rending scene in which the writer's infant son and family cat are poisoned by the extremists. From there on, the tension is unrelenting. The extremists have operators in every walk of life. Unable to trust even the police, the family flees to the backcountry then, after being discovered, into the depths of the wilderness.
Where First Blood's plot was about a deadly chase, Testament's plot is about survival and endurance under the harshest conditions, and the lengths to which a man will go to protect his family. Known for his detailed research, Morrell took a wilderness survival course before writing Testament. As a former wilderness search-and-rescue medic myself, I found his research added both a greater depth of authenticity to the book, as well as gruesome realism.
This is not an easy book to read, but it is a book well worth reading.
