Never Say Die

It's 1942, and Hitler has invaded Britain.
Twelve-year-old farm boy Benedict Flint has imagined standing up
to the Nazis ever since his father was killed and his mother taken
away.
His chance comes when he rescues top-secret information from a dying
British agent - then suddenly, he's Firebrand Flint, an accidental
real-life hero who, together with best friend Alfie, joins
the British Resistance, determined to restore the exiled teen Queen
Elizabeth.
