Grandma vs Hitler

Secret diary. War-torn country. Incredible courage. Seventeen-year-old Owen Petrov expects to be bored out of his mind when he has to accompany his immigrant grandmother back to Russia for a reunion. He is polite, but counts the hours until he can return to his comfortable suburban life back in Ohio. His boredom suddenly evaporates during their journey when she chooses to reveal a diary she's kept hidden all these years.
Owen quickly discovers that she is not the cookie-baking, sweet grandmother he's always taken for granted. Instead, her diary describes a deadly past.
