The Savage children think they lead normal, largely unspectacular lives until they unearth the heart of a shooting star on a peaceful Cornish beach.

What seems like a chance encounter compels them onto a collision course with a pandemic of dark magic so malign that it threatens their family; the true kingdom of the animals and the enchanted fae who watch over them all.

Following the path set by the Moonstone, they journey deep into a mystical realm hiding in plain sight. Here they discover personal qualities, enchanted items and allies previously unknown.

But how can they ever hope to become strong enough to face up to what lies in wait for them in the shadowy clutches of the ancient Ashridge Forest?

And how do they survive a sinister force that has hungered for them for many barren generations?
