Good evening, brave reader! Are you feeling brave enough to join Polly & Friday as they climb Goblin Mountain to battle the forces of evil? Be warned. Their adventure is full of swords & trolls & witches – & a strange thing that looks like a gherkin. & somehow that old roo-de-lally Mr Gum is mixed up in it too. Shabba me whiskers, it’s a BARMY EPIC!
