The Storm and the Minotaur by Lucy Strange
Money is scarce in George's family and so at the age of nine he has to join his father underground, hewing coal in the local mine. It's far from the dreams George had of continuing his education, and it's also a dangerous way to earn a living that has already claimed the life of his dad's older brother.
Not long after he starts work, a summer storm leads to flooding in the mine. Trapped down in the dark, George spots a shadowy figure that seems to be telling George to follow him.
Can a ghost from the past lead him back to safety, or will George meet the same fate as his long-lost uncle?
