Poppy is being transferred to an enormous new munitions complex in Gretna, on the Scottish border. Even though it means moving far away from her best friends Maggie and Annie, she is excited for the challenge.
But when she sees something in the dead of night, and suddenly the dangers of the war are no longer far away on distant shores. With the enemy hot on her heels and no idea who to trust, can Poppy save herself - and avert disaster for her country?
