Conspiracy of blood and smoke

In 1933, eighteen-year-old Gretchen, niece of Adolph Hitler, reunites with her Jewish boyfriend when she leaves the safety of England to return to Germany to investigate a murder and expose the evil of the Nazi regime. The girl known as Gretchen Whitestone has a secret: she used to be part of Adolf Hitler's inner circle. But she made an enemy of her old family friend and fled Munich, living now in England, posing as an ordinary German immigrant, and preparing to graduate from high school. But then her love, Daniel, a reporter, gets a telegram that sends him back to Germany. When she receives word that Daniel is wanted for murder, Gretchen has to face the danger she thought she'd escaped, and return to her homeland.
