A teen goes back in time to prevent his mother’s murder in this riveting read—in trade paperback for the first time.

A secret passageway that leads back in time? Jack can’t believe what he’s discovered, but it’s true: The hidden metal door in his grandfather’s house leads him to 1941. Shaken by his experience, Jack vows not to use the door again. But when his alcoholic father gets drunk one too many times, Jack witnesses his mother’s horrific death and flees back through the door. He plans to stay alive until he can reach the present and prevent his mother’s death. However, with World War II on the horizon, Jack soon finds himself fighting not only for his mother’s life, but for his own.
