Finding Richard

Joel shook his head. "No, no, no," he moaned. "That was nineteen thirty-nine, that was over seventy years ago!"
"What, mate?" said Richard. "There's something wrong with your maths. That was just last year. It's nineteen forty now."
Joel is lost in Bristol during the Blitz. Is he dreaming, or has the world gone mad? The people here seem to think it's 1940 and Hitler is trying to invade. Will Joel make it back home? Or will his new friend, Richard, get him killed looking for shrapnel on bomb sites, or dodging explosions during an air raid? Joel just wants to get out of the place and find out what on Earth is going on. But even if he does, will it be an experience Richard will let him forget?
