Sweetmeat is as old as Wales. As old as the valleys and the mountains. He was here long before humans. He was around when dragons ruled this land. Then the people came and Sweetmeat was forced to hide in the river, until he discovered that humans offered nourishment. They tasted good. They tasted sweet.

When four-year-old Nicky goes missing from a housing estate in north Wales, the local kids are sure they know what happened to him. He was taken by Sweetmeat, a creature who loves nothing more than the taste of a naughty child. But when best friends Philip and Sam set off across the valley to Sweetmeat’s lair, they have no idea that the journey will change the course of their lives forever.
