I had a problem with the bit about the chocolate in the life raft. The story changed after the two men on the raft with Louis were dead.
There was sense that here weren't many POWs at the camp. There were 750 men there.
Focusing on one man eliminated the horror of what took place in Japanese POW camps.
It wasn't a good book in my opinion. The writer didn't know enough about WWII in the Pacific Theater to write this story.
