Harley Spark is just an ordinary thirteen-year-old kid who lives with his mum, Delia. Rumour has it that his dad, Ray, is an international crime figure with a talent for nicking old, valuable things. So when Harley finds an antique Chinese vase on the footpath, something compels him to put it under his jumper and run for home. Little does he know he's about to reignite a centuries-old war between two ancient, supernatural families.
