When Kit and her best friend Binfire head to a stately home in Lincolnshire to view five ultra-rare Vixens from the Void action figures – the main exhibit at the opening of a new toy museum – they come across more than just nerds and toy-collectors. The figures are stolen from their glass case and, just as Kit and Binfire begin to get their heads around this mystery, they start to reappear, broken into pieces, left for their distraught owners to discover. And that's when the real killings start.
