Somehow, they've managed to keep their friendship a secret. Until one day, when everything changes ...' (Synopsis)

'Polly the witch and Buster the monster shouldn’t be friends. And they definitely shouldn’t be on the run from almost everyone in town. But when Polly is called to the Hollow Valley Mines – the forbidden, haunted mines – by her magic stones, these two best friends have a big decision to make. Do they stay hidden and safe, or risk it all to save the day?'
