O'Brien, Johnny

Fifteen-year-old Jack is sent to 1914 Europe as a pawn in the battle between his long-lost father, who has built a time machine, and a secret network of scientists who want to prevent him from trying to use it to change history for the better. Includes historical notes.

To thwart their arch-enemy, Pendlesharp, and his misguided notion of changing history, schoolboy Jack Christie and his friend Angus travel back in time to foil a plot to assassinate Elizabeth I, meeting playwright Christopher Marlowe and a young actor named William Shakespeare along the way.
