If you don't know about Reverse Falls I can tell you. ( Note from Present me now, this book is shit but somehow people like it and want more )

A soon-to-be man named Fritz Richtofen Schultz is thrown into the Second World War along with his two childhood best friends Karl and Günter. All three of them are German Messerschmitt Bf - 109 pilots and they will witness and experience things of which they could only imagine happen not too long ago. I found the book cover art from Armyna on ArteMilitarNaval.es.
