Blood and Honor
If you enjoyed W. E. B. Griffin's Honor Bound, you should segue with pleasure into this involving sequel. Set in Buenos Aires in 1943, it follows the adventures of three American soldiers as they think and fight their way through a complex story about Nazi sympathizers, dedicated supporters of the Allied cause, and other people just trying to stay alive. As we've come to expect from his many books about soldiers and cops, Griffin knows how to use the small moments of crime and war to invent a compelling canvas for his solid characters.
