Part 3. Exercise
This is a magnificent book. It details the horrors of war and the inhumane conditions POWs were forced to face, but it also is a carefully crafted tale of friendship, and how people can thrive in the most unlikely places. I disagree with the reviewer who thinks it is a depressing book - it is a novel of the human spirit, with a dash of good old capitalism thrown in for good measure.Again, it is a wonderful book. It will stay with you for a long time.
Answer:
Positive
