In the forests of Dartmoor, creatures of legend hide in the treetops, swim in the rivers, and roam the hills... but they're invisible to those who don't know how to look properly. Scrubby, a child of the fairies swapped at birth with a human infant, has inherited this wonderful gift. With a little help from the Wise Man of Wistman's Wood, his eyes are opened to the secrets of the moors. And even when he is forced to leave his forest for Victorian London, his forest never leaves him...

After leaving their beloved Dartmoor to find work in the capital, it's not long before the Johnsons realize that London is not the promised land after all. The lower classes are worked to the bone and struggle to survive, and their dreams of equality are brutally shattered. Scrubby's father is fatally injured during the Bloody Sunday catastrophe, and further tragedy is not far behind. But Scrubby and his sister, Sheela, keep moving forward and find work to survive. And in his new job down in the mines, Scrubby will find friendship, love... and chaos

The mysterious red-eyed man's plan succeeded: the dragon woke from its slumber and the mine collapsed, leaving but a few protected survivors. Following the trial of fire, Scrubby has now passed the trial of earth, and the trial of water is on the horizon. But Scrubby is not the only one whose life is in danger... With the police discovering a string of bloody murders, it seems a new killer is in town. But is he a man, or a demon?

With the body count rising, the London press is having a field day with "Spring-Heeled Jack," the terrifying killer of the East End. But Scrubby knows this wave of terror is not an isolated phenomenon... The upper crust of this huge industrial city has given in to its basest desires and has awoken an ancient evil. It won't be long until Scrubby is forced to confront the person responsible for his father's death. He'll need all the help he can get to defeat this man with the soul as black as coal.

The diabolical Sir Charles Warren is dead, but Spring-Heeled Jack, the demon awoken by his Hellfire Club, is still roaming the streets of London, engulfing the city in darkness and blood. It can mean only one thing: the border with the underworld is fading, and Scrubby, the changeling child, is going to have to rid the mortal world of this demon. To do this, he will need to discover the truth behind his origins and enter limbo, between fantasy and reality...
