"England, 1944: As Lizzie looks around her twin brother's room, she's in a state of shock. In the middle of the night Ed vanished, leaving no forwarding address. Lizzie knows that he was tormented daily by what he witnessed at Dunkirk four years before, helping his father steer their tiny boat to rescue thousands of injured soldiers. He was never the same after that. Then, Ed's call-up letter arrives. Instead of being assigned to one of the forces, he's been told to report for work at a coal mine--one of fifty thousand 'Bevin boys' chosen to help produce the fuel to power the nation through the war. If he fails to turn up he will be arrested and tried as a deserter. Staring at his abandoned clothes and knowing how alike they are, Lizzie realises there is a way to save him. Arriving for training, she meets a fellow Bevin boy named Peter and is instantly drawn to his quiet, thoughtful nature, so unlike the other men who share her dormitory. And as the two start to adapt to their new lives underground, they develop a strong bond. Lizzie knows the risks she is taking to save her brother. If she grows too close to Peter her secret will almost certainly be revealed, and they will both be imprisoned. But with the war raging and her beloved country at risk, how much is Lizzie prepared to sacrifice to save those she loves the most?"--Provided by publisher.
