Input: I'll be honest, this is a depressing book. But it is about a depressing subject. This is a semi-autobiographical look at the author's internment in one of the Japanese's POW camps, Changi. It is a statement on the ingenuity and cunning of mankind, but also of its brutality. If you're looking for a quick, solid read, this is it.
Output:
Positive
