World War Two Adventure. Part of the Yankee Filer series, A Yankee Flier Over Berlin is a history of an American pilot's experience fighting the Luftwaffe in Europe, during World War II. Before there was a term "Young Adult" literature, these books were written as adventure novels for teen boys. Action packed and filled with examples of bravery, The Yankee Flier Books are a perfect complement to a WWII study unit.
