Join Minnie for an epic Viking adventure across the sea! Minnie's mum is getting married to her teacher (eww!), which of course means she needs the perfect gift. But when searching the tunnels beneath the school for the ideal present, Minnie stumbles across ten-year-old Denys, Dennis's Viking ancestor, who has been stuck living in the tunnels for centuries. Denys longs to leave his dank prison, but the tunnels are the only thing stopping him from ageing. However, there is a treasure buried in Ireland that could break his curse, so it's lucky that Minnie's mum just so happens to be getting married there, isn't it? Join Minnie for an epic adventure to Ireland. Will they break the curse before Denys gets too old? Perfect for kids whose parents have got divorced and are remarrying – or just want to read a mega-funny story!
