Normally I pay not a jot of attention - but this is a particularly beautiful cover don't you think.
From the Blurb:
In 1930s Munich, danger lurks behind dark corners, and secrets are buried deep within the city. But Gretchen Müller, who grew up in the National Socialist Party under the wing of her "uncle" Dolf, has been shielded from that side of society ever since her father traded his life for Dolf's, and Gretchen is his favorite, his pet.
Uncle Dolf is none other than Adolf Hitler. And Gretchen follows his every command.
