When Darkness Fell: Their Darkest Hour

Eighteen-year old Wolfgang Khouri paused his World War 2 video game and said, "Hitler was a dummkopf. I could have done better," and then went off to his regular mixed martial arts class. But when his scientist father invents a time machine to prevent his parents' painful divorce, Wolfgang invites his beautiful sister, Margot, and travels back in time to Munich, 1933.

Out of spite, Wolfgang and Margot drag Peter, their too-perfect Christian stepbrother, into the time machine with them and throw him into Dachau concentration camp. Nazis need Jesus too, Peter reasons, and escapes. Peter sets out to overthrow the Third Reich with love and his guitar.

As his perfectly redesigned Panther tanks blitz into western Europe, Wolfgang learns that Winston Churchill and the British Empire did not rise to power by playing fair.
