Its about this young RAF officer in WWII who's brother was kidnapped by a German woman about 9 previous of the start of the book. The brother, Tony, who was around 2 years old at the time, was taken to Germany and raised in the German fashion and when old enough attended rallies etc in support of Nazi Germany eventually becoming one off the Hitler Youth. Anyhow, long story short, Tony, growing up being called Max gets captured by the English and meets up with Dym (The RAF guy) though Tony believes himself to be of pure German heritage. Dym then, after much careful thinking and several clues discovers that Max (a.k.a. Tony) is his younger long lost brother Tony. Tony is then taken into Dyms custody and lives at Dyms childhood home with many of Dyms relations and also several borders living there, Dym visits every few weeks when on leave. Tony is disgusted at being held a prisoner by the "Mad English" and has the grueling task of waiting at lest till the end of the war till he can to return to Germany and Dym has the grueling task of persuading Max that he is not Max Eckermann but really Tony Ingleford.
I was a little over halfway through till Vellvin thinks "oh that looks like a cool book lets read it" and thus for 2-3 days every now and then it would be 'stolen' from me until I recovered it from the 'theif' and then a argument would begin on who was rightful to have the book. Then one of us would get it then it would be stolen......etc. Finally I finished it and randomly picked a new book of the shelf last night "The Reb and the Redcoats" and coincidentally it is by the same author as Enemy Brothers!!
The comforting thought is that Vellvin has already read it!!!!
